---------------------------+----------------------------------
When converting Sage complex numbers to PARI, we should return a PARI
`t_REAL` if the original number was actually real. This fixes a problem
with `ellwp()` in #15767. In PARI's floating point model, the number
`1e-19 + 0.0*I` has less precision than the real `1e-19`.
It is also consistent with the PARI philosophy of returning simplified
types (examples: `(1.1*I)^2` and `ellj(1.1*I)` in PARI gives real
numbers).
