ARM: update peephole optimization. More condition codes are included when deciding whether to remove cmp after a sub instruction. Specifically, we extend from GE|LT|GT|LE to GE|LT|GT|LE|HS|LS|HI|LO|EQ|NE. If we have "sub a, b; cmp b, a; movhs", we should be able to replace with "sub a, b; movls". rdar: 11725965 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159166 91177308-0d34-0410-b5e6-96231b3b80d8
