mflr is kind of expensive on Power version smaller than 10, so we should schedule the store for the mflr's def away from mflr. In epilogue, the expensive mtlr has no user for its def, so it doesn't matter that the load and the mtlr are back-to-back. Reviewed By: RolandF Differential Revision: https://reviews.llvm.org/D137423
