amdgcn: Fix attributes for LLVM-12 [PR 100208]
This should work for a wider range of LLVM 12 variants now.
More work required for LLVM 13 though.

PR target/100208
* config.in: Regenerate.
* config/gcn/gcn-hsa.h (A_FIJI): New define.
(A_900): New define.
(A_906): New define.
(A_908): New define.
(ASM_SPEC): Use A_FIJI, A_900, A_906 and A_908.
* config/gcn/gcn.c (output_file_start): Adjust attributes according
to the assembler capabilities.
