[PATCH] D70183: Detect source location overflow due includes

[Diogo N. Sampaio via Phabricator via cfe-commits]

Rebased

Created a early exit when a source location overflow is detected,
avoiding further processing or reaching other assert failures.
For that, it was required to create a 'Failure' kind for includes,
as well add return points along the callstack.

      

Added test that works in both release and debug modes.
