Chris Lattner 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.
