Probably best reviewed by someone who has more familiarity with RISCVTargetDefEmitter, but I took a look anyway.

I think this direction is OK, though I can't help but feel moving from the ISA naming strings to the more verbose listing of features is a bit of a regression in terms of ease of reading. I guess we'd be stuck with a recursive dependency if we wanted tablegen to be able to parse RISC-V ISA strings, as we'd be relying on the tablegenned extension definitions.
