Update "clrq" convenience instruction to be slightly faster From Doug Masten <doug@dougmasten.com> who says: This is not a bug fix but a very tiny optimization for the "clrq" convenience instruction in LWTOOLS. This patch changes it from "clra; clrb; tfr d,w" to "clrd; clrw". The new instructions now take 2 clock cycles less for a total of 4 clock cycles.
