cross/gcc-*: upgrade to 14.2.0-r4 (MR 5722)

Quite a messy upgrade due to changes in both abuild and in the upstream
gcc APKBUILD breaking various things. Pmbootstrap also seems to
misbehave in GitLab CI making it difficult to validate.

Manual fixups:
* Set !tracedeps - changed behavior in abuild
* Manually add "so:" dependencies to avoid issues with !tracedeps set
  (becomes obvious with crossdirect)
* Add back makedepends="$makedepends_build $makedepends_host"
* Disable move of some files into usr/lib to avoid
  ERROR: gcc-aarch64-14.2.0-r4: trying to overwrite usr/lib/libgcc_s.so.1 owned by libgcc-14.2.0-r4.

[ci:skip-build] # pmbootstrap bugs will prohibit this from building
                # anyways, don't even attempt

+From 2cf89ae83225f932b226cd57ef2d083a59bcf8a3 Mon Sep 17 00:00:00 2001
+From: Richard Biener <rguenther@suse.de>
+Date: Tue, 6 Aug 2024 14:56:26 +0200
+Subject: [PATCH] tree-optimization/116166 - forward jump-threading going wild
+
+Currently the forward threader isn't limited as to the search space
+it explores and with it now using path-ranger for simplifying
+conditions it runs into it became pretty slow for degenerate cases
+like compiling insn-emit.cc for RISC-V esp. when compiling for
+a host with LOGICAL_OP_NON_SHORT_CIRCUIT disabled.
+
+The following makes the forward threader honor the search space
+limit I introduced for the backward threader.  This reduces
+compile-time from minutes to seconds for the testcase in PR116166.
+
+Note this wasn't necessary before we had ranger but with ranger
+the work we do is quadatic in the length of the threading path
+we build up (the same is true for the backwards threader).
+
+	PR tree-optimization/116166
+	* tree-ssa-threadedge.h (jump_threader::thread_around_empty_blocks):
+	Add limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	* tree-ssa-threadedge.cc (jump_threader::thread_around_empty_blocks):
+	Honor and decrement limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	(jump_threader::thread_across_edge): Initialize limit from
+	param_max_jump_thread_paths and pass it down to workers.

+From 2cf89ae83225f932b226cd57ef2d083a59bcf8a3 Mon Sep 17 00:00:00 2001
+From: Richard Biener <rguenther@suse.de>
+Date: Tue, 6 Aug 2024 14:56:26 +0200
+Subject: [PATCH] tree-optimization/116166 - forward jump-threading going wild
+
+Currently the forward threader isn't limited as to the search space
+it explores and with it now using path-ranger for simplifying
+conditions it runs into it became pretty slow for degenerate cases
+like compiling insn-emit.cc for RISC-V esp. when compiling for
+a host with LOGICAL_OP_NON_SHORT_CIRCUIT disabled.
+
+The following makes the forward threader honor the search space
+limit I introduced for the backward threader.  This reduces
+compile-time from minutes to seconds for the testcase in PR116166.
+
+Note this wasn't necessary before we had ranger but with ranger
+the work we do is quadatic in the length of the threading path
+we build up (the same is true for the backwards threader).
+
+	PR tree-optimization/116166
+	* tree-ssa-threadedge.h (jump_threader::thread_around_empty_blocks):
+	Add limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	* tree-ssa-threadedge.cc (jump_threader::thread_around_empty_blocks):
+	Honor and decrement limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	(jump_threader::thread_across_edge): Initialize limit from
+	param_max_jump_thread_paths and pass it down to workers.

+Date: Tue, 6 Aug 2024 14:56:26 +0200
+Subject: [PATCH] tree-optimization/116166 - forward jump-threading going wild
+
+Currently the forward threader isn't limited as to the search space
+it explores and with it now using path-ranger for simplifying
+conditions it runs into it became pretty slow for degenerate cases
+like compiling insn-emit.cc for RISC-V esp. when compiling for
+a host with LOGICAL_OP_NON_SHORT_CIRCUIT disabled.
+
+The following makes the forward threader honor the search space
+limit I introduced for the backward threader.  This reduces
+compile-time from minutes to seconds for the testcase in PR116166.
+
+Note this wasn't necessary before we had ranger but with ranger
+the work we do is quadatic in the length of the threading path
+we build up (the same is true for the backwards threader).
+
+	PR tree-optimization/116166
+	* tree-ssa-threadedge.h (jump_threader::thread_around_empty_blocks):
+	Add limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	* tree-ssa-threadedge.cc (jump_threader::thread_around_empty_blocks):
+	Honor and decrement limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	(jump_threader::thread_across_edge): Initialize limit from
+	param_max_jump_thread_paths and pass it down to workers.

+From 2cf89ae83225f932b226cd57ef2d083a59bcf8a3 Mon Sep 17 00:00:00 2001
+From: Richard Biener <rguenther@suse.de>
+Date: Tue, 6 Aug 2024 14:56:26 +0200
+Subject: [PATCH] tree-optimization/116166 - forward jump-threading going wild
+
+Currently the forward threader isn't limited as to the search space
+it explores and with it now using path-ranger for simplifying
+conditions it runs into it became pretty slow for degenerate cases
+like compiling insn-emit.cc for RISC-V esp. when compiling for
+a host with LOGICAL_OP_NON_SHORT_CIRCUIT disabled.
+
+The following makes the forward threader honor the search space
+limit I introduced for the backward threader.  This reduces
+compile-time from minutes to seconds for the testcase in PR116166.
+
+Note this wasn't necessary before we had ranger but with ranger
+the work we do is quadatic in the length of the threading path
+we build up (the same is true for the backwards threader).
+
+	PR tree-optimization/116166
+	* tree-ssa-threadedge.h (jump_threader::thread_around_empty_blocks):
+	Add limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	* tree-ssa-threadedge.cc (jump_threader::thread_around_empty_blocks):
+	Honor and decrement limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	(jump_threader::thread_across_edge): Initialize limit from
+	param_max_jump_thread_paths and pass it down to workers.

+From 2cf89ae83225f932b226cd57ef2d083a59bcf8a3 Mon Sep 17 00:00:00 2001
+From: Richard Biener <rguenther@suse.de>
+Date: Tue, 6 Aug 2024 14:56:26 +0200
+Subject: [PATCH] tree-optimization/116166 - forward jump-threading going wild
+
+Currently the forward threader isn't limited as to the search space
+it explores and with it now using path-ranger for simplifying
+conditions it runs into it became pretty slow for degenerate cases
+like compiling insn-emit.cc for RISC-V esp. when compiling for
+a host with LOGICAL_OP_NON_SHORT_CIRCUIT disabled.
+
+The following makes the forward threader honor the search space
+limit I introduced for the backward threader.  This reduces
+compile-time from minutes to seconds for the testcase in PR116166.
+
+Note this wasn't necessary before we had ranger but with ranger
+the work we do is quadatic in the length of the threading path
+we build up (the same is true for the backwards threader).
+
+	PR tree-optimization/116166
+	* tree-ssa-threadedge.h (jump_threader::thread_around_empty_blocks):
+	Add limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	* tree-ssa-threadedge.cc (jump_threader::thread_around_empty_blocks):
+	Honor and decrement limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	(jump_threader::thread_across_edge): Initialize limit from
+	param_max_jump_thread_paths and pass it down to workers.

+From 2cf89ae83225f932b226cd57ef2d083a59bcf8a3 Mon Sep 17 00:00:00 2001

+Date: Tue, 6 Aug 2024 14:56:26 +0200
+Subject: [PATCH] tree-optimization/116166 - forward jump-threading going wild
+
+Currently the forward threader isn't limited as to the search space
+it explores and with it now using path-ranger for simplifying
+conditions it runs into it became pretty slow for degenerate cases
+like compiling insn-emit.cc for RISC-V esp. when compiling for
+a host with LOGICAL_OP_NON_SHORT_CIRCUIT disabled.
+
+The following makes the forward threader honor the search space
+limit I introduced for the backward threader.  This reduces
+compile-time from minutes to seconds for the testcase in PR116166.
+
+Note this wasn't necessary before we had ranger but with ranger
+the work we do is quadatic in the length of the threading path
+we build up (the same is true for the backwards threader).
+
+	PR tree-optimization/116166
+	* tree-ssa-threadedge.h (jump_threader::thread_around_empty_blocks):
+	Add limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	* tree-ssa-threadedge.cc (jump_threader::thread_around_empty_blocks):
+	Honor and decrement limit parameter.
+	(jump_threader::thread_through_normal_block): Likewise.
+	(jump_threader::thread_across_edge): Initialize limit from
+	param_max_jump_thread_paths and pass it down to workers.
