Douglas Gregor e8bbc12152 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).

them into the clang namespace.

Chris Lattner 8806e32f16 Rename CGT::VerifyFuncTypeComplete to isFuncTypeConvertible since 
it is a predicate, not an action.  Change the return type to be a bool,
not the incomplete member.  Enhace it to detect the recursive compilation
case, allowing us to compile Eli's testcase on llvmdev:

struct T {
 struct T (*p)(void);
} t;

into:

%struct.T = type { {}* }

@t = common global %struct.T zeroinitializer, align 8

Anders Carlsson d6f1518cc9 Fix another regression from the "skip vtable pointer initialization" 
optimization. Make sure to require a vtable when trying to get the address
of a VTT, otherwise we would never end up emitting the VTT.

Eli Friedman 49a94b1c7c Add an implementation of thunks for varargs methods. The implementation is a bit messy, but it is correct as long as the method in question doesn't use indirect gotos. A couple of possible alternative implementations are outlined in FIXME's in this patch. rdar://problem/8077308 .

John McCall 358d056c14 We were emitting construction v-tables with internal linkage all the time. 
Emit them instead with the linkage of the VTT.

I'm actually really ambivalent about this;  it's what GCC does, but outside
of improving code size (if the linkage is coalescing), I'm not sure it's
at all relevant.  Construction vtables are naturally referenced only by the
VTT, which is itself only referenced by complete-object constructors and
destructors;  giving the construction vtables possibly-external linkage is
important if you have an optimization that drills through the VTT to a
reference to a particular construction vtable which it cannot just emit
itself.

Douglas Gregor 1baf38f5a6 On Mac OS X, the presence of an 'availability' attribute for that 
platform implies default visibility. To achieve these, refactor our
lookup of explicit visibility so that we search for both an explicit
VisibilityAttr and an appropriate AvailabilityAttr, favoring the
VisibilityAttr if it is present.
