computed?
In {{{/sage/rings/number_field/number_field.py}}} (as per #11869) the
parts
* "# List of candidates for K(x)" and
* "# Find a common field F into which KF and LF both embed."
are independent. The first can be very slow, while the second is likely to
fail. So I propose to swap these two parts.
