keepFramePointer is implemented as a target independent method... if you're going to get rid of the call here, you should also get rid of the interface from TargetFrameLowering.  (No other in-tree target implements it anyway, but we want to keep the code clean, and give an obvious error in case there is someone with an out-of-tree dependency.)
