Chris Lattner 0fd8ee4995 turn on memset idiom recognition by default. Though there are still lots of ... limitations, this kicks in dozens of times in the 4 specfp2000 benchmarks, and hundreds of times in the int part. It also kicks in hundreds of times in multisource. This kicks in right before loop deletion, which has the pleasant effect of deleting loops that *just* do a memset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122664 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-01 20:39:18 +00:00
