AMDGPU: Stop running assembler tests with default cpu

It does not make sense to assemble for the default target.
Add one that shows the behavior. It is treated as a tahiti
alias without instructions which were later removed, and needs
to be treated as wave64. We should probably turn this into a hard
error though.
