Option to exclude unreachable branches
Option to exclude unreachable branches

Adding new option, '--exclude-unreachable-branches' that
allows to exclude branches in certain lines from coverage report.
This is intended to solve the problem of reporting uncovered
branches on some compiler-generated code which is essentially dead,
that is to say, cannot be exercised by testing suites.
