Rewrites some if statements into boolean expressions.

if (<cond>) { <expr_stmt>; } => <cond> && <expr_stmt>

if (<cond>) { <then_expr_stmt>; } else { <else_expr_stmt>; } =>
   <cond> ? <then_expr_stmt> : <else_expr_stmt>

Also supports lifting return statement:

if (<cond>) { return <expr1>; } else { return <expr2>; } =>
  return <cond>?<expr1>:<expr2>;

Reduces code size by a tiny amout (approx. 0.5%) mostly because this optimization create a lot of opportunities for inliner to kick in.
