Bump the Mesa-internal LLVM (kept in feeds/video/libs/llvm/) from
21.1.3 to 22.1.5, and the matching SPIRV-LLVM-Translator from
21.1.1 to 22.1.2.
The SPIRV-LLVM-Translator's major version tracks LLVM's major,
so it caps which LLVM major we can move to. Khronos has now
shipped v22.1.2 (latest in the 22.x series), allowing the LLVM
major bump.
Mesa 26.0.6 sets only a minimum LLVM (>= 18 / 15 / 8 depending
on the requested driver set); no upper bound, so LLVM 22.x is
acceptable.
Two LLVM 22 build-system changes need adapting in the Makefile:
1. LIBCLC_TARGETS_TO_BUILD got stricter target name validation:
'amdgcn--amdhsa' is rejected in favour of 'amdgcn-amd-amdhsa',
and the 32-bit nvptx ('nvptx--', 'nvptx--nvidiacl') targets
were dropped (the 64-bit equivalents remain).
2. libclc bytecode now installs under
'usr/lib/clang/<major>/lib/libclc/' rather than the previous
'usr/share/clc/'. Adjust the SPIR-V .spv copy in Build/Install
to source from the new location (a glob on the major version
avoids re-touching this on the next bump).
The downstream 100-allow-arc-target.patch still applies unchanged.
