d05634d5 - [VectorCombine] Fold bitwise operations of bitcasts into bitcast of bitwise operation (#137322)

[VectorCombine] Fold bitwise operations of bitcasts into bitcast of bitwise operation (#137322) Currently, LLVM fails to convert certain pblendvb intrinsics into select instructions when the blend mask is derived from complex boolean logic operations. This occurs even when the mask is ultimately based on sign-extended comparison results, preventing further optimization opportunities.
