Comment:
I only did some cleanup in `matrix_space.py` and
`matrix_generic_dense.pyx`. And there is a substantial gain in speed! The
tiny modification in #18213 to `NumberField.__cmp__` actually makes a much
bigger difference.
I did not solve the problem of the matrix space being rebuilt every time.
