[llvm-branch-commits] [clang] [clang-tools-extra] [clang] NFC: Clear some uses of MemberPointerType::getClass (PR #131965)

Just did a spot-check, but the uses I saw all seemed reasonable.

There ARE a few cases I saw where it did a `cast` to `RecordType` then a `getDecl`, so this loses the assert, but I think that is still reasonable.
