More if-statment optimizations in JsStaticEval.

Adds two extra optimizations:

 - Empty, but present else statements are pruned:

if (x) {doSomething();} else {} -> if (x) {doSomething();}

 - If statements with empty "then" conditions are inverted:

if (x) {} else {doSomething()} -> if (!x) {doSomething();}
