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. llvm-svn: 218004
