Perform zero-initialization of virtual base classes when emitting
...
a zero constant for a complete class. rdar://problem/8424975
To make this happen, track the field indexes for virtual bases
in the complete object. I'm curious whether we might be better
off making CGRecordLayoutBuilder *much* more reliant on
ASTRecordLayout; we're currently duplicating an awful lot of the ABI
layout logic.

A CGRecordLayout object persists. Since its contained types may
...
refer to opaque types, they must be held via PATypeHolders. I'm
not sure why this hasn't blown up before.

Go back to asking CodeGenTypes whether a type is zero-initializable.
...
Make CGT defer to the ABI on all member pointer types.
This requires giving CGT a handle to the ABI.
It's way easier to make that work if we avoid lazily creating the ABI.
Make it so.
