Petar Avramovic 0d572c41f9 AMDGPU\GlobalISel: remove amdgpu-global-isel-risky-select flag (#83426) ...

AMDGPUInstructionSelector should no longer attempt to select S1 G_PHIs.
Remove MIR test that attempts to inst-select divergent vcc(S1) G_PHI.
Lane mask merging algorithm for GlobalISel is now responsible for
selecting divergent S1 G_PHIs in AMDGPUGlobalISelDivergenceLowering.
Uniform S1 G_PHIs should be lowered to S32 G_PHIs in reg bank select
pass. In summary S1 G_PHIs should not reach AMDGPUInstructionSelector.
