This is a partial patch set attempting to set things in the
right direction for both the UXL and RV128 patch sets.
Notable addition for v3 is the treatment of [MS]STATUS.SD. Because this
bit changes position depending on XLEN, it's better to split it out.
But since it's read-only and computable from [MS]STATUS.{FS,XS}, it
is even better to not store it at all. I noticed this while reading
Frank's RVV patches which add VS to be included in SD.

* Fix CONFIG_ typo.
* Fix ctzw typo.
* Mark get_xlen unused (clang werror)
* Compute MSTATUS_SD on demand.
Changes for v2:
* Set mxl/sxl/uxl at reset.
* Set sxl/uxl in write_mstatus.
