Chris Lattner 5bcdf24a50 Handle global variable definitions which change the type of a definition, such as: 
extern int x[];
void foo() { x[0] = 1; }
int x[10];
void bar() { x[0] = 1; }

Chris Lattner c8dbe1e5d6 Warn about unsupported codegen with the diags machinery, giving us: 
t.c:3322:5: warning: cannot codegen this yet
    __asm__ ("bswap   %0" : "+r" (_data));

Oliver Hunt aefc8fd415 Support initalisers for more than just int-typed static variables. 
We now use the CodeGenModule logic for generating the constant 
initialiser expression, so happily further initialiser fixes should 
automatically work for statics as well.

Devang Patel 75ef2f0b45 Take 2. 
Make target info available to clang code generator.  This is far from complete but this helps clang codegen module make progress.

At the moment target triplet and target description strings are hard coded in clang::TargetInfo

Hartmut Kaiser 7078da8e58 Updated VC++ build system. 
Silenced some VC++ warnings.
Had to rephrase a partial specialization of the IntrospectionTrait struct in SerializationTest.cpp, please review.
Added a compiler specific workaround in IdentifierTable.h. Is that the way to fix this kind of issues?

Steve Naroff 9def2b15c1 Phase 2 of making the Decl class more lightweight... 
Move Identifier/Loc instance variables (and associated getters/setters) down from Decl to ScopedDecl/FieldDecl.

Objc AST's can now inherit from Decl without getting instance variables and types that are C specific. For now, I am keeping NextDeclarator, since I believe it may be useful to ObjC. If not, it can be moved later.

Chris Lattner 9e47ead594 Implement codegen support for lowering "library builtins" like __builtin_isinf 
to their corresponding library routines (e.g. isinf).  This allows us to handle
all the stuff in macos math.h, and other stuff as it's added to *Builtins.def.
