Original PR: #130537 Originally reverted due to revert of dependent commit. Relanding with no changes. This changes the MemberPointerType representation to use a NestedNameSpecifier instead of a Type to represent the base class. Since the qualifiers are always parsed as nested names, there was an impedance mismatch when converting these back and forth into types, and this led to issues in preserving sugar. The nested names are indeed a better match for these, as the differences which a QualType can represent cannot be expressed syntatically, and they represent the use case more exactly, being either dependent or referring to a CXXRecord, unqualified. This patch also makes the MemberPointerType able to represent sugar for a {up/downcast}cast conversion of the base class, although for now the underlying type is canonical, as preserving the sugar up to that point requires further work. As usual, includes a few drive-by fixes in order to make use of the improvements.
