[MS ABI] NV bases may indirectly contain covariant thunks from V Bases

A class might contain multiple ways of getting to a vbase, some of which
are virtual and other non-virtual.  It may be the case that a
non-virtual base contains an override of a method in a vbase.  This
means that we must carefully pick between a set of nvbases to determine
which is the best.

As a consequence, the findPathForVPtr algorithm is considerably simpler.
