Douglas Gregor bcfd1f55bf Extend the ASTContext constructor to delay the initialization of 
builtin types (When requested). This is another step toward making
ASTUnit build the ASTContext as needed when loading an AST file,
rather than doing so after the fact. No actual functionality change (yet).

Daniel Dunbar e26bdb91b7 IRgen: Add a -fuse-register-sized-bitfield-access option, for testing. 
- Changes bit-field access policy to try to use (aligned) register sized accesses.

The idea here is that by using larger accesses we expose more coalescing
potential to the backend when we have situations like adjacent bit-fields in the
same structure (which is common), and that the backend should be smart enough to
narrow the accesses down when no coalescing is done or when it is shown not to
be profitable.

Douglas Gregor 575a1c9dc8 Introduce Type::isSignedIntegerOrEnumerationType() and 
Type::isUnsignedIntegerOrEnumerationType(), which are like
Type::isSignedIntegerType() and Type::isUnsignedIntegerType() but also
consider the underlying type of a C++0x scoped enumeration type.

Audited all callers to the existing functions, switching those that
need to also handle scoped enumeration types (e.g., those that deal
with constant values) over to the new functions. Fixes PR9923 /
<rdar://problem/9447851>.

Anders Carlsson eb9d81dff9 When laying out bases in, always try the "base subobject" LLVM type. If it 
turns out that a field or base needs to be laid out in the tail padding of
the base, CGRecordLayoutBuilder::ResizeLastBaseFieldIfNecessary will convert
it to an array of i8.

I've audited the new test results to make sure that they are still valid. I've
also verified that we pass a self-host with this change.

This (finally) fixes PR5589!

John McCall 9b7da1c46d 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.
