Subject: [LoopVectorize] Use CreateAligned(Load|Store)
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=4df656952a8127f152cd7d440ed5f133dc6f6f56;p=oota-llvm.git

[LoopVectorize] Use CreateAligned(Load|Store)

IRBuilder has CreateAligned(Load|Store) functions; use them and we don't need
to make a second call to setAlignment.

No functionality change intended.
