[PATCH] D97970: [RISCV] Make the hasStdExtM() check in RISCVInstrInfo::getVLENFactoredAmount emit a diagnostic rather than an assert.

[Fraser Cormack via Phabricator via llvm-commits]

frasercrmck added a comment.

This is better than an assert, but do we absolutely require M? Couldn't we fall back to compiler-rt, for instance?
