File: precompute hash
Most files are going to be looked up into a set or dictionary. Precompute
the hash so that we only need to do so once and we can also use it to
quickly weed out unequal objects.
On a QEMU build, the time spent in __eq__ and __hash goes respectively
from 3.110s to 2.162s and from 0.648s to 0.299s. Even larger gains are
obtained by the next patch.
