ARM: Clean up optimizeCompare in peephole, no functional change.
Use getUniqueVRegDef. Replace a loop with existing interfaces: modifiesRegister and readsRegister. Factor out code into inline functions and simplify the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159470 91177308-0d34-0410-b5e6-96231b3b80d8
