  [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

(cherry picked from commit d66b53738a29fb3a0551167efcb8d35320a539b7)
