Chen Zheng	eb7d16ea25	[PowerPC] make expensive mflr be away from its user in the function prologue ... 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.
