[libTooling] Add `ifBound`, `elseBranch` RangeSelector combinators.
Summary:
Adds two new combinators and corresponding tests to the RangeSelector library.
* `ifBound` -- conditional evaluation of range-selectors, based on whether a
given node id is bound in the match.
* `elseBranch` -- selects the source range of the else and its statement.
