Bitwise merge.

It works like a multiplex: the bits in the mask operand decide whether the corresponding bit of the result is taken from op0 or op1.
Or explained differently: it does what pick does on the operand level on the bit level.


merge(op op0) → op r0

operands: like Identity [xx:x]

merge(u mask, u bits0, u bits1) → op r0

encoding: merge(op op0) , exuArgs(op arg0, op arg1)
