[llvm] [AMDGPU] Remove v_cmp_t_* and v_cmp_f_* for GFX12 (PR #75498)

[Jay Foad via llvm-commits]

https://github.com/jayfoad created https://github.com/llvm/llvm-project/pull/75498

Also v_cmpx_t_* and v_cmpx_f_*

No GFX12 encoding was added for these, so this patch just adds tests
that they are not recognized by the assembler.
