Mike Stump aa08da7906 Refactor a bit and remove some FIXME audit markers, now that the code
has been audited for correctness.

Mike Stump 78696a70bf Implement more of the inductive case for vtable layout involving
virtual base primaries and improve the layout of classes with virtual
bases.  WIP.

Hey, I've decided I want a change to FileCheck, I need to ensure that
the group is together, nothing in between.  Can we change it to check
the match line is from the line immediately following the last matched
line, if the source for the matched line is immediately after the
source for the previously matched line?

// CHECK: 1
// CHECK: 2
// CHECK: 3

// CHECK: 4
// CHECK: 5
// CHECK: 6

would require 1 2 and 3 to be continuous in the output, and 4 5 and 6
to be continuous.

Anders Carlsson 28a5fa29f3 Take #pragma pack into account when laying out structs. Fixes rdar://problem/7095436.

Anders Carlsson 68e0b68289 Introduce a new PragmaPack attribute, and use it for #pragma pack. The PackedAttr now only represents __attribute__((packed)).
This is necessary because #pragma pack and __attribute__((packed)) have different semantics. No functionality change yet, but this lays the groundwork for fixing a record layout bug.

Mike Stump 2509480813 Fixup object layout when we have a primary base (it goes first). Start preping for
virtual base layout.

Mike Stump d8fe7b2792 Calculate the primary base class better and use that when laying down
the vtable.  Still a work in progress.

Mike Stump 57724c2f7e Update based upon comments. Explain why we have an assert.

Mike Stump 44b8e90369 We'll also need a vtable pointer if we have virtual bases.

Mike Stump 3dc7eb9440 Add ability to layout the vtable pointer in trivial cases. I noticed
that we would silently do bad things with virtual bases in the layout
code, so, we just turn them off.  When people do better things with
them, we can turn them back on.

Ted Kremenek c23c7e6a51 Change uses of:
Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsRecordType() -> Type::getAs<RecordType>()
  Type::getAsPointerType() -> Type::getAs<PointerType>()
  Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>()
  Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>()
  Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>()
  Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>()
  Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsTagType() -> Type::getAs<TagType>()
  
And remove Type::getAsReferenceType(), etc.

This change is similar to one I made a couple weeks ago, but that was partly
reverted pending some additional design discussion. With Doug's pending smart
pointer changes for Types, it seemed natural to take this approach.

table as it has its own place now.
