[MS ABI] Reuse getVFPtrOffsets instead of using getClassAtVTableLocation

getClassAtVTableLocation hunts through virtual bases without using the
MDC layout which is indicative of a bug.

Instead, reuse the getVFPtrOffsets machinery to calculate which
subobject within the MDC is responsible for the vfptr.
