The current way creates a fallacy that checking for
`PolicyAttrs == TAIL_AGNOSTIC` is implicitly equivalant to
`TAIL_AGNOSTIC_MASK_UNDISTURBED`.

This way of checking is wrong when the default policy is not TAMU.
As this patch-set is changing the default from TAMU to TAMA, we need
to perform this refactoring before chaning the default.

Depends on D141768 <https://reviews.llvm.org/D141768>.
