[SLSR] garbage-collect unused instructions Summary: After we rewrite a candidate, the instructions used by the old form may become unused. This patch cleans up these unused instructions so that we needn't run DCE after SLSR. Test Plan: removed -dce in all the SLSR tests Reviewers: broune, meheff Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D9101 llvm-svn: 235410
