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 09153c0a8c Build enough support for aggregates to be able to compile this: 
void test(int A, _Complex float Y) {
  _Complex float X;
  X = X;

Chris Lattner b6984c4854 Hook up global function and variable handling. We can now compile: 
int X, bar(int,int,int);
short Y;

double foo() {
  return bar(X, Y, 3);
}

into:

@X = external global i32                ; <i32*> [#uses=1]
@Y = external global i16                ; <i16*> [#uses=1]

define double @foo() {
entry:
        %tmp = load i32* @X             ; <i32> [#uses=1]
        %tmp1 = load i16* @Y            ; <i16> [#uses=1]
        %promote = sext i16 %tmp1 to i32                ; <i32> [#uses=1]
        %call = tail call i32 @bar( i32 %tmp, i32 %promote, i32 3 )             ; <i32> [#uses=1]
        %conv = sitofp i32 %call to double              ; <double> [#uses=1]
        ret double %conv
}

declare i32 @bar(i32, i32, i32)

Chris Lattner 2ccb73bc8b Refactor CodeGenTypes out to CodeGenModule so it can be used for functions 
and globals.

Chris Lattner 2052bc8107 Split type analysis out to its own file, now the integer constant expr evaluation 
is ready.

Chris Lattner 23b7eb677d Finally bite the bullet and make the major change: split the clang namespace 
out of the llvm namespace.  This makes the clang namespace be a sibling of
llvm instead of being a child.

The good thing about this is that it makes many things unambiguous.  The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier.  IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.
