__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);

Add codegen support and test for said casts.

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

Now, at AST level record info is maintained by ASTRecordLayout class.
Now, at code gen  level record info is maintained by CGRecordLayout class.

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?

Generate code for static variables that don't have initializers. Also, report an error if a static initializer is not constant.

all the stuff in macos math.h, and other stuff as it's added to *Builtins.def.

This patch temporarily breaks compound assignment operators, but greatly simplifies many
things.
