TableGen: Switch from a std::map to a DenseMap in CodeGenSubRegIndex. NFC This mapping is between pointers, which DenseMap is particularly good at. Most targets aren't really affected, but if there's a lot of subregister composition this can shave off a good chunk of time from generating registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@279875 91177308-0d34-0410-b5e6-96231b3b80d8
