Mark the Int_eh_sjlj_dispatchsetup pseudo instruction as clobbering all registers. Previously, the register we being marked as implicitly defined, but not killed. In some cases this would cause the register scavenger to spill a dead register. Also, use an empty register mask to simplify the logic and to reduce the memory footprint. rdar://12592448 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167499 91177308-0d34-0410-b5e6-96231b3b80d8
