Re-apply r276044/r279124/r305516. Fixed a problem where we would refuse to place spills as the very first instruciton of a basic block and thus artifically increase pressure (test in test/CodeGen/PowerPC/scavenging.mir:spill_at_begin) This is a variant of scavengeRegister() that works for enterBasicBlockEnd()/backward(). The benefit of the backward mode is that it is not affected by incomplete kill flags. This patch also changes PrologEpilogInserter::doScavengeFrameVirtualRegs() to use the register scavenger in backwards mode.
