Inlining produces unnecessary local variables and assignments about apparat HOT 3 CLOSED

Apparat will not perform copy propagation when using TDSI. The local variables 
have to be created because the following is valid code:

function add(x: int): void {
 x += 1;
 return x;
}

var y: int = 0;
add(y)
trace(y)

If no extra variables would be created, the code would trace "1" but should 
trace "0". Therefore variables are created and an additional optimization phase 
would be required to get rid of them. That could and is already implemented in 
the TAAS code as a phase, but since there is no complete ABC frontend or ABC 
backend (and I am no longer interested in writing it) your best chance will be 
to use MacroExpansion instead since no additional variables are created.

Issue 62 has been merged into this issue.

Thanks.

I originally use Inlined because the documentation led me to believe that I 
absolutely  may not use return values with macros.
I thought I would try anyway and was surprised to see that it works just fine 
and does exactly what I want.
