Implement autoderef for function calls. This is important since we are going to be making functions noncopyable soon, which means we'll be seeing a lot of boxed functions. (f)(...) is really just too heavyweight. Doing the autodereferencing was a very little bit tricky since trans_call works with an lval* of the function whereas existing autoderef code was not for lvals. 2011-07-01 04:52:05 -05:00			`fn main() {`
