This slipped through the regalloc2 operand code update in #4811: the CvtFloatToUintSeq pseudo-instruction actually clobbers its source. It was marked as a "mod" operand in the original and I mistakenly converted it to a "use" as I had not seen the actual clobber. The instruction now takes an extra temp and makes a copy of `src` in the appropriate place. Fixes #4840.
