Alyssa Rosenzweig cc82dba1ca OpcodeDispatcher: use mvn for AF with constants 
This reduces pointless constant usage. For now, it's no net change to
instcountci, but it should make it easier to get wins later. Hopefully.

like SUB.

due to RA silliness, this is a loss for inst count but a win for cycles.

Alyssa Rosenzweig 6994fc3a01 IR,OpcodeDispatcher,JIT: fuse adcs flags 
The usual tricks, also requires introducing a bare adc op to optimize adcs to,
but we wanted that anyway!

Also support a zero source, so we can calculate "foo + CF" in one instruction to
optimize the "lock adc" cases.
