[LLVM part] These patches rename the loop unrolling and loop vectorizer metadata such that they have a common 'llvm.loop.' prefix. Metadata name changes: llvm.vectorizer.* => llvm.loop.vectorizer.* llvm.loopunroll.* => llvm.loop.unroll.* This was a suggestion from an earlier review (http://reviews.llvm.org/D4090) which added the loop unrolling metadata. Patch by Mark Heffernan. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211710 91177308-0d34-0410-b5e6-96231b3b80d8
