Log Message:
Make can_trust_pointer_alignment() always return false on STRICT_ALIGNMENT
archs - gcc 4.5 is not able to properly track alignment and backporting
the fix from 4.6/4.7 is not feasible (according to upstream).
See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46483 for details.
Fixes PR toolchain/46865.
