The concept here seems right; we should treat funclet entry as if it clobbers all registers.

I'm not sure about the implementation here; we should have some common utility that encompasses this.  Making MachineLICM compute its own version of which registers are live seems liable to lead to bugs.  I guess getBeginClobberMask() is supposed to encompass what this is checking for?
