Both in one patch, and the test case that Chris didn't commit last
time is in there too...

I'll split the patch up if somebody wants it split."

I've added a tests/CodeGen directory, and a test for this case that
used to fail and now passes."

Not having this prevented promoting float arguments to double when passed
into printf, for example.
