Re-apply r97667 but with a little bit of thought put into the patch. This implements a special DenseMapInfo trait for DenseMap<MachineInstr*> that compare the value of the MachineInstr rather than the pointer value. Since the hashing and equality test functions ignore defs it's useful for doing CSE kind optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97678 91177308-0d34-0410-b5e6-96231b3b80d8
