[SLP] Propagate 'nontemporal' attribute into vectorized instructions.

Authored by mzolotukhin on Aug 20 2015, 1:47 PM.



Currently we drop nontemporal attribute when vectorizing instructions, and this
patch fixes it. It hasn't been a problem, because there weren't cases when we
needed to vectorize scalar instructions with nontemporal attribute. But I'm
working on adding language attribute 'attribute((nontemporal)' to front-end,
after which we'll encounter such cases.
