shim between the TargetTransformInfo immutable pass and the Subtarget via the TargetMachine and Function. Migrate a single call from BasicTargetTransformInfo as an example and provide shims where TargetMachine begins taking a Function to determine the subtarget. No functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218004 91177308-0d34-0410-b5e6-96231b3b80d8
