[PATCH] D38718: Patch to Bugzilla 20951

[Erik Viktorsson via Phabricator via cfe-commits]

erikv created this revision.

Submitting a patch to Bugzilla 20951.

Simply replaced the function call IgnoreImpCasts to IgnoreParenImpCasts which seems to more appropriate.
I also had to modify a test cast in test/Sema/conditional-expr.c
