Implement infrastructure for unary operator emission.
Implement basic logical not support. We now compile:
register short X;
if (!X) {
into:
%tmp = load i16* %X ; <i16> [#uses=1]
%tobool = icmp ne i16 %tmp, 0 ; <i1> [#uses=1]
%lnot = xor i1 %tobool, true ; <i1> [#uses=1]
zext i1 %lnot to i32 ; <i32>:0 [#uses=1]
%tobool1 = icmp ne i32 %0, 0 ; <i1> [#uses=1]
br i1 %tobool1, label %ifthen, label %ifend
