  Log Message:
  -----------
  [PhaseOrdering][X86] Copy backend horizontal min/max reduction tests to phaseordering (#194601)

As discussed on #194473 - add middleend test coverage to ensure we're
creating vXi8/vXi16 llvm.vector.reduce calls to ensure we can lower to
PHMINPOS instructions

Also demonstrates that we're still not matching partial reduction
patterns in vectorcombine
