Adding support for overlapping ranges to RangeMap.

Browse Source 
When enabled, adding of a new range that overlaps with an existing one can be a successful operation.  The range which ends at the higher address will be shrunk down by moving its start position to a higher address so that it does not overlap anymore.

This change is required to fix http://crbug/611824.  The actual fix will come in a separate CL.
