Although the *_fast_* functions are certainly meant to be faster than
their unqualified alternatives, they are faster only because they are

isl_blk: don't reuse overly large blocks for small allocations
We usually allocate a large number of small objects, but occasionally
we may allocate one or more big objects. The original caching code
could reuse a cached huge object for a small allocation.
This is fine if the object would grow later, but if it remains
small, then we may end up consuming and wasting a lot of memory,
especially if these objects are long-lived.
Now we only a memory block if it is at most twice as big as the desired
size. This may result in some large objects sticking around in the cache,
so we evict objects from the cache after a while.
Finally, we don't reuse any cache elements for initially zero sized
allocations, but instead check the cache when the objects first growns
to a non-zero size.

isl_tab_pip.c: add_lexmin_eq: remove misguided optimizations
After adding a pair of inequalities corresponding to the equality,
the code tries to reduce the dimensionality of the problem by
removing a column. If one of the added constraints happens to have
been pivoted into a column, then it can easily be removed.
Otherwise, the code tries to pivot the row into a column and
then remove the column.
This pivot may disrupt the lexico-positiveness of the columns however.
At the first least, the code should check that the pivot entry
is negative, but it should also avoid pivoting out a column corresponding
to a parameter.
Since this optimization shouldn't have that much of an effect anyway,
we choose here to just remove it for now.

isl_map_identity: take dimension specification of map as input
Before, isl_basic_map_identity and isl_map_identity would take
the dimension specification of a set as input, but this could be
confusing for users. Moreover, by taking the specification of a map
as input, we can now also construct canonical mappings between spaces
with the same dimension, but with different names or internal structure.

transitive closure: project out parameters when any constraints are impure
The resulting delta set can lead to extra constraints on the path,
resulting in a possibly more accurate approximation.

isl_set_lift: preserve structure of space
Before, we would simply add extra variables to the dimension specification,
if needed, destroying any internal structure. Now, we retain the original
dimension specification as the domain of a wrapped map.
