This ticket implements
[http://trac.sagemath.org/sage_trac/ticket/12514#comment:5 the suggestion]
that was discussed in #12514. The idea is to be helpful to new users and
coax them into doing the computations over the right fields.

Comment:
Patch attached. I haven't changed the `LU` and `QR` functions for two
reasons:
1. I don't quite know what to cache in those functions there.
2. The behavior of `RR` and `CC` is already documented in those functions.
