__builtin_overload takes 2 or more arguments:
0) a non-zero constant-expr for the number of arguments the overloaded 
   functions will take
1) the arguments to pass to the matching overloaded function
2) a list of functions to match.

The return type of __builtin_overload is inferred from the function whose args
match the types of the arguments passed to the builtin.  For example:

float a;
float sinf(float);
int   sini(int);

float b = __builtin_overload(1, a, sini, sinf);

Says that we are overloading functions that take one argument, and trying to 
pass an argument of the same type as 'a'.  sini() does not match since it takes
and argument of type int.  sinf does match, so at codegen time this will turn
into float b = sinf(a);

Enable CodeGen for member expressions based on call expressions returning aggregate types. This enables expressions like 'foo().member.submember'.

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.

support any sort of expr, add a new EmitAnyExpr routine.

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.
