This allow recognition of when a ptest was emitted as an any condition
and allows for extra optimization to be done later.

This addresses missing optimizations from D137716 <https://reviews.llvm.org/D137716> and D137718 <https://reviews.llvm.org/D137718>, and
partially D137717 <https://reviews.llvm.org/D137717>.

Depends on D137716 <https://reviews.llvm.org/D137716>, D137717 <https://reviews.llvm.org/D137717>, D137718 <https://reviews.llvm.org/D137718>
