Properly process try/finally blocks.
In some circumstances, try/finally block can actually catch the exception:
function f() {
try {
throw 42;
} finally {
return 0;
}
}
Therefore when propagating exception to v8::TryCatch, we must be sure
there is no try/finally blocks as well.
When bulding the messages we should be more conservative and expect that
any v8::TryCatch with no JS try/catch in between can potentionally
be the right exception handler.
Plus various minor refactorings.
