Chandler Carruth 93228f6199 [vectorizer] Tweak the way we do small loop runtime unrolling in the ... loop vectorizer to not do so when runtime pointer checks are needed and share code with the new (not yet enabled) load/store saturation runtime unrolling. Also ensure that we only consider the runtime checks when the loop hasn't already been vectorized. If it has, the runtime check cost has already been paid. I've fleshed out a test case to cover the scalar unrolling as well as the vector unrolling and comment clearly why we are or aren't following the pattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200530 91177308-0d34-0410-b5e6-96231b3b80d8		2014-01-31 10:51:08 +00:00
