[Headers][X86] Enable constexpr handling for pmulhw/pmulhuw intrinsics (#152540)
This patch updates the pmulhw/pmulhuw builtins to support constant
expression handling - extending the VectorExprEvaluator::VisitCallExpr
handling code that handles elementwise integer binop builtins.
Hopefully this can be used as reference patch to show how to add future
target specific constexpr handling with minimal code impact.
I've also enabled pmullw constexpr handling (which are tagged on
#152490) as they all use very similar tests.
I've also had to tweak the MMX -> SSE2 wrapper as undefs are not
permitted in constexpr shuffle masks
Fixes #152524
