[PATCH] [ms-cxxabi] Implement member pointer conversions

[Reid Kleckner]

Any thoughts on this?  This was a bunch of fun to work out.  =D

The commit message I wrote is all wrong about the reinterpret_cast
corner case.  For reinterpret_cast, you have to do null conversion,
but all other conversions are impl-defined, and the easiest conversion
is a no-op.
