Justin Bogner ea4e88c5cf 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.
