e11664a0ef Rename classes and collections that maintain record layout information. 
Now, at AST level record info is maintained by ASTRecordLayout class.
Now, at code gen  level record info is maintained by CGRecordLayout class.

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?

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.

things.

cbfc73b26c Split complex arithmetic codegen out from aggregate codegen. 
This means that we get rid of tons of intermediate allocas.  For
example:

void foo(double _Complex a, double _Complex b) {
   a = b+a+a;
}

this used to have 4 temporary allocas, now it has zero of them.
This also simplifies the individual visitor methods because they
now can all operate on real/imag pairs instead of having to 
load/store all over the place.

6278e6ac30 start splitting out aggregate value computation from EmitExpr into EmitAggExpr. 
aggregate value and scalar expression computation are very different, this
gets them away from each other.  This causes a temporary regression on some
complex number examples.

81a9688e93 Implement codegen for __builtin_choose_expr. For example: 
struct X { int A; };

void foo() {
  struct X s;
  int i;
  i = __builtin_choose_expr(0, s, i);
}

compiles to:

        %tmp = load i32* %i             ; <i32> [#uses=1]
        store i32 %tmp, i32* %i

wow :)

73ab9b3c14 implement lvalue to rvalue conversion for ocuvector components. We can now compile stuff 
like this:

typedef __attribute__(( ocu_vector_type(4) )) float float4;
float4 test1(float4 V) {
  return V.wzyx+V;
}

to:
_test1:
        pshufd  $27, %xmm0, %xmm1
        addps   %xmm0, %xmm1
        movaps  %xmm1, %xmm0
        ret

and:

_test1:
        mfspr r2, 256
        oris r3, r2, 4096
        mtspr 256, r3
        li r3, lo16(LCPI1_0)
        lis r4, ha16(LCPI1_0)
