[llvm-readobj] Update tests because of changes in llvm-readobj behavior This patch updates tests using llvm-readobj and llvm-readelf, because soon reading from stdin will be achievable only via a '-' as described here: https://bugs.llvm.org/show_bug.cgi?id=46400. Patch with changes to llvm-readobj behavior is here: https://reviews.llvm.org/D83704 Differential Revision: https://reviews.llvm.org/D83912 Reviewed by: jhenderson, MaskRay, grimar

[AMDGPU] Don't mark the .note section as ALLOC Marking a section as ALLOC tells the ELF loader to load the section into memory. As we do not want to load the notes into VRAM, the flag should not be there. On AMDHSA, .note is still marked as ALLOC, apparently this is currently needed for OpenCL (see https://reviews.llvm.org/D74995). Differential Revision: https://reviews.llvm.org/D76278
