Add more functions to the target library information.
I discovered a few more missing functions while migrating optimizations from the simplify-libcalls pass to the instcombine (I already added some in r167659). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168501 91177308-0d34-0410-b5e6-96231b3b80d8
