Dummy block is an empty block with no predecessors.

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.

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

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.

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.

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 :)

Rename AddrLabel and OCUVectorComponent -> AddrLabelExpr and OCUVectorElementExpr respectively.  This is for consistency with other expr nodes end with *Expr.

    vec2.x = f;

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)
        lvx v3, r4, r3
        vperm v3, v2, v2, v3
        vaddfp v2, v3, v2
        mtspr 256, r2
        blr

We can now codegen:

  vec4.xy;

as nothing!
