<summary>Changes</summary>

Adding the missing wwm-regalloc=fast option in 4 more tests
that already specify -sgpr-regalloc=fast and -vgpr-regalloc=fast.
For consistency, the same preference should be applied to the
wwm-regalloc pipeline as well.
This is a follow-up to #<!-- -->184190 which addressed the same issue in
attr-amdgpu-flat-work-group-size-vgpr-limit.ll.
