Albeit that it requires nuanced shift/roll semantics, eliminates CL constant.
...
Shifts and rolls are already slightly semantically special for being undefined for values greater than 8/16/32 — i.e. in some implementations they don't even use the entirety of CL, just the low five bits. Which makes me feel a little better.
The upside of no ambiguity between eCX size 1 and CL justifies the trade.
