Fix a rare corner case bug which exposed a serious block API generation
when initialized variable is a byref block variable and is referenced recursively

API for byref variable before API for its initializer. We will have this

Remove the IndirectPrimary parameter in LayoutVirtualBases; it's already there as a member variable.

Get rid of the LayoutBaseNonVirtually; it was used to lay out a base either as a non-virtual base or a virtual base.

Fix calculation of whether a member function needs a thunk in construction vtables.

Change the 'super' messaging API in the rewriter.
Fixes radar 7738452.

Suppress the tag when printing an ElaboratedType if the language options
claim this is C.  We don't make ElaboratedTypes in C, but sometimes
the language options during pretty-print lie to us.

The rewriter should really be fixed to not rely on how types are pretty-printed,
though.

Remove '#if 0' code.  Lazy compound values have proven their worth.
