This patch splits the mask argument checking out of
vectorizable_mask_load_store, so that a later patch can use it in both
vectorizable_load and vectorizable_store. It also adds dump messages
for false returns. This is mostly useful for the TYPE_VECTOR_SUBPARTS
check, which can fail if pattern recognition didn't convert the mask
properly.
