[PATCH] D107290: [PoC][RISCV] Add support for the vscale_range attribute

[Fraser Cormack via Phabricator via llvm-commits]

This may be as far as we can take this patch without exposing RVV vectors bit control to the user/driver and having to worry about the concerns that spring from that: linking objects compiled with different RVV vector bits options, LTO, etc.

I believe that with the current state of the patch, the default, hard-coded `vscale_range` with values mandated by the spec, combined with the existing backend options for overrides, mean we're not losing any functionality.
