void foo() {
  int x
  if (x) {
  }
}

We now emit:

a.c:5:3: error: parse error
  if (x) {
  ^
1 diagnostic generated.

instead of:

a.c:5:3: error: parse error
  if (x) {
  ^
a.c:9:1: error: expected '}'

^
2 diagnostics generated.

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.

significantly faster and actually reduces the amount of code in the system.
This also allows for future visitor changes.
