> I couldn't figure out a robust way to translate from CSR register defs to the sysreg number. Oddly, getName() on VLENB returns EH_LABEL? I suspect we have something missing elsewhere.

That sounds like you asked TargetInstrInfo for the name rather than TargetRegisterInfo. EH_LABEL is instruction number 4. VLENB is register number 4.
