The assertion verifying that a newly computed value matches what is already cached used stripPointerCasts() to strip bitcasts, however the values can be not only pointers, but also vectors of pointers. That is problematic because stripPointerCasts() doesn't handle vectors of pointers. This patch introduces an ad-hoc utility function to strip all bitcasts regardless of the value type.
