Jit64: Improve cmpXX imm handling

In the past, the register cache would contain either a host register or
an immediate (or neither) for a given guest register. Jit64::cmpXX would
roll with whichever one it got. But now that PR 12134 is merged, the
register cache can contain a host register at the same time as an
immediate. This gives us an optimization opportunity in Jit64::cmpXX.
Some paths are more efficient when we use an immediate and some paths
are more efficient when we don't, so to generate the best code, we
should carefully choose if we want an immediate or not rather than
leaving it to the register cache.
