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 ;) llvm-svn: 156233
