[clang][Sema] Allow abstract declarators to specify cv-qualified function types as per CWG1417 (#209836)

Abstract declarator contexts (specifically `DeclaratorContext::TypeName`) now properly bypass this restricted rule, allowing cv-qualified function types in `__typeof__` while maintaining restrictions in other contexts like `typeid`, `sizeof`, C-style casts, and `new` expressions per CWG1417.

Git commit 5565740f2367093b89481ba7371adf820971977d by GitHub (on behalf of Arthur Eubanks) on 27/07/2026 at 17:39..
[lld] Don't drop RELR relocations for late-added GOT entries (#211911)

In #208959 we started dropping RELR relocations for late-added GOT
entries when reverting x86-64 GOTPCRELX relaxations in
X86_64::relaxOnce.

There is a separate unrelaxation bug where if the object files didn't
have any relocations of a certain type, we'd prune .relr.dyn (or even
.rela.dyn). Will be addressed separately.

[llvm-objcopy] Fix AMDGPU arch string in test: amdgpu not amdgcn

llvm-readobj reports 'Arch: amdgpu' for EM_AMDGPU ELF files
(the generic AMDGPU ELF format used by elf64-amdgpu). The test
was incorrectly expecting 'amdgcn', which is the AMDGCN-specific
arch string used by ROCm HSA code objects.

[llvm-objcopy] Remove unnecessary AMDGPU ELF flag from test

The EF_AMDGPU_MACH_AMDGCN_GFX900 flag was not needed in the test input.
The test only verifies that llvm-objcopy correctly sets EM_AMDGPU machine
type, 64-bit class, and little-endian encoding -- none of which depend on
the e_flags value. Use the same approach as all other architectures in
the test (no explicit FLAGS, defaulting to <none>).
