[PATCH] D115921: [RISCV] Refactor the RISCV ISA extension info and target features to support multiple extension version

[Jessica Clarke via Phabricator via cfe-commits]

jrtc27 added a comment.

Do not bring back V draft 0.7. It is gone, it will never be supported again by LLVM under that name. The standard extension namespace is reserved for ratified extensions and development snapshots only, not old drafts vendors decided to ship. For those, non-standard extension names are needed.
