  Log Message:
  -----------
  [clang][PAC] Fix builtins that claim address discriminated types are bitwise compatible (#154490)

A number of builtins report some variation of "this type is compatibile
with some bitwise equivalent operation", but this is not true for
address discriminated values. We had address a number of cases, but not
all of them. This PR corrects the remaining builtins.

Fixes #154394
