Add a new target hook "predictableSelectIsExpensive".
This will be used to determine whether it's profitable to turn a select into a branch when the branch is likely to be predicted. Currently enabled for everything but Atom on X86 and Cortex-A9 devices on ARM. I'm not entirely happy with the name of this flag, suggestions welcome ;) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156233 91177308-0d34-0410-b5e6-96231b3b80d8
