Remove unnecessary exception and suspend checks.

1. Post exception check, when 2 consecutive branches are return and exception
unwind, respectively, merge these 2 branches as the caller doesn't care
the return value when an exception is pending..

2. If the method is leaf, we can elide the suspend check.

3. Also, move suspend checks to be before pushing shadow frame for the sake of "1"
and for reducing code size (Multiple returns).
