  -----------
  Regenerate code as of VMMaker.oscog-nice.2714

Fix incorrect IA32/X64 encoding of operands LZCNT (ClzRR) and BSR instructions.

I did swap the operands, destReg is in reg/opcode (RO) field, and maskReg (source) is in r/m (RM) field.
------
VMMaker.oscog-nice.2713

Fix bug in LargeInteger division: instantiation of quotient (quo) may fail and thus require a proper guard.

It may happen: I did report some crash when testing huge integer division at http://smallissimo.blogspot.com/2019/05/tuning-large-arithmetic-thresholds.html

Fix a copy/paste glitch JumpCarry/JumpNoCarry in #setsConditionCodesFor:
We only ever use JumpZero so far, so it's benign.
