Do not vectorize loops on Core2 that need to use unaligned
vector load/stores.
* tree-vect-stmts.c (is_vector_load_store_slow): New function.
(vectorizable_load): Return false if the load
is unaligned and slow.
(vectorizable_store): Ditto.
* target.def (TARGET_SLOW_UNALIGNED_VECTOR_MEMOP): New target hook.
* doc/m.texi.in: Document new target hook:
TARGET_SLOW_UNALIGNED_VECTOR_MEMOP
* doc/m.texi: Regenerate.
* config/i386/i386.c (ix86_slow_unaligned_vector_memop): New function.
(TARGET_SLOW_UNALIGNED_VECTOR_MEMOP): New macro.
