Subject: [PATCH 1/5] [RISCV] Add support for new unprivileged extensions
defined in profiles spec
This adds minimal support for 7 new extensions that were defined as a part of
the RISC-V Profiles specification here:
https://github.com/riscv/riscv-profiles/blob/main/profiles.adoc#7-new-isa-extensions
As stated in the specification, these extensions don't add any new features but
describe existing features. So this patch only adds parsing and subtarget
features.
