This PR relands #122992. A reland was attempted before (#123853), but it [failed to pass the `sanitizer-aarch64-linux-bootstrap-hwasan` buildbot](https://github.com/llvm/llvm-project/pull/123853#issuecomment-2608389396) due to the test `llvm/test/CodeGen/SPIRV/opencl/reflect-error.ll` The issue has since been patched thanks to @vitalybuka, so the PR is safe to reland without any changes. See https://github.com/llvm/llvm-project/pull/125599#discussion_r1966650839 and https://github.com/llvm/llvm-project/pull/125599#discussion_r1966650839
