1. Align bitmanip instructions with v.1.00 and draft v.0.93 of the spec …

   In particular:
   - Zbb: Rename pcnt* instructions to cpop*
   - Zbs: Rename sb* instructions to b*
   - Zbe: Rename bext*/bdep* insctructions to bcompress*/bdecompress*.
     Stricly speaking this only happens as part of v.0.94. But without this
     change, there are two bext instructions (the other one from Zbs due to
     renaming sbext to bext).
   - Zbp: Re-add slo[iw], sro[iw]. These are still listed in v.0.93 and even
     v.0.94.
   - All: Rename *u.w instructions to *.uw
   - Zbp: fix XLEN for xperm.w
