`mangleCXXRecordDecl` should add class types to the substitution dictionary unless it is called by `mangleCXXCtorVTable` (see https://github.com/llvm/llvm-project/pull/109970 for why that is needed). This fixes a mis-compile caused by https://github.com/llvm/llvm-project/pull/132401, which started calling `mangleCXXRecordDecl` in `CXXNameMangler::mangleType(const MemberPointerType *T)`. rdar://149307496
