  Changed paths:
    M llvm/lib/Target/X86/X86ISelLowering.cpp
    M llvm/test/CodeGen/X86/umax.ll

  Log Message:
  -----------
  [X86] Lower vector umax(x,1) -> sub(x,cmpeq(x,0))

With suitable BooleanContent handling we could move this to TargetLowering::expandIntMINMAX, but this is good enough for X86

Fixes #61225
