John McCall 7a9aac2d9f Abstract out everything having to do with member pointers into the ABI 
class;  they should just be completely opaque throughout IR gen now,
although I haven't really audited that.

Fix a bug apparently inherited from gcc-4.2 where we failed to null-check
member data pointers when performing derived-to-base or base-to-derived
conversions on them.

Chris Lattner 217e056e40 implement rdar://7432000 - signed negate should codegen as NSW. 
While I'm in there, adjust pointer to member adjustments as well.

Anders Carlsson bcb2e4cb63 Don't try to explicitly zero out bit-fields.

Anders Carlsson da265b8d63 When null-initializing bases with data member pointers, don't assert on virtual bases. Just initialize them to null.

Anders Carlsson 5b94443b16 Really fix PR7139. There was one boost test that we still failed, and my first fix broke self-host.

Anders Carlsson da1641cd12 Rename CodeGenFunction::EmitMemSetToZero to EmitNullInitialization. Handle setting null data member pointers correctly. Fixes PR7139.

Anders Carlsson be48c548c5 Correctly initialize bases with member pointers. This should fix PR6441 but that test case is a bit weird and I'd like to investigate further before closing that bug.

Anders Carlsson 65c6d541dd Make sure that value-initialized pointers to data members are initialized correctly.

Anders Carlsson 259688ce29 Move pointer to data member emission to CodeGenModule and use it in CGExprConstant. Fixes PR5674.
