  [clang] diagnose invalid member pointer class on instantiation

This moves the diagnostic for member pointers pointing into
non-class into BuildMemberPointer, so that it can be
used from RebuildMemberPointer, when instantiating templates.

Also adds a minor tweak to the diagnostic when the member pointer is anonymous,
which was previously untested.

Also reverts https://github.com/llvm/llvm-project/pull/132501, which
disabled a failing test due to the regression which is now fixed.

No changelog, since this fixes a regression which has not been released
yet.

Fixes https://github.com/llvm/llvm-project/issues/132494
