Fix a vftable mangling bug

We need to walk the class hierarchy twice: once in depth-first base
specifier order for mangling and again in depth-first layout order for
vftable layout.

Vftable layout seems to depend on the full path from the most derived
class to the base containing the vfptr.

Fixes PR21031.
