amdgcn: Add gfx90a support
Attached is an attempt to update invoke.texi
And to update the gcc-13/changes.html. Regarding the latter, I have to
versions – the first is more readable, the latter makes more clear where
to use it, but reads much worse. – Pick one or suggest a better one.
OK for the two patches?

PS: I was thinking of mentioning that GCN now requires llvm-mc of LLVM
13.0.1 or higher (during build + installed as assembler) but I then
thought that changes.html is not the best place and there is an error
during build, stating what is needed.
