* Fix sanitizer/67258 by cherry picking upstream patchtrippels2015-09-092-3/+8
| | | | | | | | | | | | | | | | | | | | | PR sanitizer/67258 * ubsan/ubsan_type_hash.cc: Cherry pick upstream r244101. Upstraem patch: commit 1d2477faafda9ad2cc19927b3c31efd22747f013 Author: Alexey Samsonov <vonosmas@gmail.com> Date: Wed Aug 5 19:35:46 2015 +0000 [UBSan] Fix UBSan-vptr false positive. Offset from vptr to the start of most-derived object can actually be positive in some virtual base class vtables.
