  Changed paths:
    M llvm/lib/Target/X86/X86ISelLowering.cpp

  Log Message:
  -----------
  [X86] PromoteMaskArithmetic - explicitly attempt to constant fold zext(c) instead of relying on getNode()

Don't rely on isBuildVectorOfConstantSDNodes/getNode to constant fold, this could also help in cases where the constant is behind a bitcast.

Noticed while investigating #80668
