Reduce the amount of Regex VM Instruction code
Merge all lookarounds into the same instruction, merge splits, merge
literal ignore case with literal...
Besides reducing the amount of almost duplicated code, this improves
performance by reducing pressure on the (often failing) branch target
prediction for instruction dispatching by moving branches into the
instruction code themselves where they are more likely to be well
predicted.
