This reverts commit
6373465b50e93c0a8df20fdefe572a2eaebb8490.
It was thought that handling nested dims would be easier when
constructin isl_dims instead of isl_basic_maps during construction.
However, it turns out that using isl_basic_maps works just fine
and avoids carrying around the equalities separately.
Moreover, if we want to be able to parse integer divisions,
then we need to store their definitions somewhere and
an isl_basic_map is the most appropriate way to do so.

rename isl_pw_qpolynomial_fold_add to isl_pw_qpolynomial_fold_fold
The new name is more consistent with the naming of
isl_qpolynomial_fold_fold. Furthermore, it makes sense to perform
addition on isl_pw_qpolynomial_folds, so we prefer to use
the name isl_pw_qpolynomial_fold_add for such a function.

isl_map_gist: also perform gist in universe context
Originally, it didn't make sense to gist in a universe context,
because there were no constraints with respect to which the gist
could be computed. However, since the more aggressive gist of
d5e1701 (isl_basic_map_gist: be more aggressive in removing constraints)
some contraints can get removed even in a universe context.
