workflows/release-binaries: Run this job once a week to catch regressions (#176008)
This will increase the chances that we can have this job working for the
first release candidate.
[RFC][Clang][AMDGPU] Emit only delta target-features to reduce IR bloat
Currently, AMDGPU functions have `target-features` attribute populated with all default features for the target GPU. This is redundant because the backend can derive these defaults from the `target-cpu` attribute via `AMDGPUTargetMachine::getFeatureString()`.
In this PR, for AMDGPU targets only:
- Functions without explicit target attributes no longer emit `target-features`
- Functions with `__attribute__((target(...)))` or `-target-feature` emit only features that differ from the target's defaults (delta)
The backend already handles missing `target-features` correctly by falling back to the TargetMachine's defaults.
A new cc1 flag `-famdgpu-emit-full-target-features` is added to emit full features when needed.
Example:
Before:
```llvm
attributes #0 = { "target-cpu"="gfx90a" "target-features"="+16-bit-insts,+atomic-buffer-global-pk-add-f16-insts,+atomic-fadd-rtn-insts,+ci-insts,+dl-insts,+dot1-insts,+dot2-insts,..." }

workflows/release-binaries: Fix attestation artifact name (#176417)
We were contructing the attestation artifact name using the arch and the
OS of the current runner instead of using the runner that the builds
were done on. This led to a conflict in artifact names between all the
release binary jobs.

bootimage: allow MD Makefiles to add a port-specific boot partition
Some ports require an additional port-specific boot partition even
for live images so that firmware ROMs can load a bootloader.
For example, luna68k ROMs require old 4.3-BSD style FFS, and hp300
ROMs require an HP LIF format diretory entries.
Add a USE_MDBOOTPART switch and adjust size/offset calculations and
image concatination so MD liveimage Makefiles can provide own rules
to build and populate the boot-partition image.
prepare for /usr/bin/gfortran.
in the Makefile, add fortran to the list of languages to configure.
add configure-target-libquadmath and configure-target-libgfortran
to the listof mknative targets to invoke.
while here also remove some HAVE_GCC < 12 support.
in mknative-gcc, remove ancient dead get_libg2c(), grab a couple
more libgomp variables (will be used to replace some hard coded
things and also adds the gomp/fortran portions), add new get
functions for libquadmath and libgfortran, and also fetch the rest
of the necessary variables.
[libc] Remove ballot on slab find (#176606)
Summary:
This negatively impacts performance, while the other changes in the
initial PR slightly improved it. This was originally done to make Volta
independent thread scheduling work, but that doesn't seem to work
correctly all the time either so we should make this faster.

[Clang][AMDGPU] Handle `wavefrontsize32` and `wavefrontsize64` features more robustly
We should also not allow `-wavefrontsize32` and `-wavefrontsize64` to be specified at the same time.

[mlir][vscode] Add angle bracket support to MLIR language configuration (#176602)
Add angle brackets (<>) to brackets, autoClosingPairs, and
surroundingPairs for better editing of types like tensor<3xf32>. Also
add colorizedBracketPairs for visual distinction between nested bracket
types.
[mlir][vscode] Fix PDLL grammar character class regex (#176601)
The character class [aA-zZ_0-9] incorrectly matches characters between
ASCII 90-97 (Z-a range), which includes: [ \ ] ^ _ `. This should be
[a-zA-Z_0-9] for proper identifier matching.
