D2: Applied function type from D1 frontend that got removed in D2, it's critical for member function type to be correct. Fixed a bunch of type discrepancies in druntime object.di vs. genobj.d . Disabled (#if 0) some potentally very large type dumps for -vv . Updated classinfo and typeinfo generation for D2, almost complete now. Added finer grained checks for vtbl type mismatching, aids debugging.
