When logical expression is evaluated in the control context (e.g. if (cond) { ... })
avoid materializing a boolean value and then dispatching on it. Instead connect
true and false successors directly to then and else branches.
This CL also improves IL generated when logical expression is evaluated for value
(e.g. x = (cond)): we similarly avoid materializing intermediate results and also
avoid comparisons that are not needed, e.g. when evaluating x = A && B we construct
graph x = A ? B : false, instead of x = A ? (B == true ? true : false) : false style
of graph.

with a try-catch got optimized and the exception/stacktrace variables
got captured.
