isl_basic_map_gist: drop irrelevant constraints from the context
The context may contain constraints on variables that do not even
appear in the input basic map. The constraints therefore cannot
be exploited to simplify the input and only serve to make some
of the internal computations more expensive, in particular the
computation of the affine hull of the intersection of input and context
and the emptiness checks used in the final determination of
the redundancy of a constraint.
It's therefore more efficient to remove those irrelevant constraints.

isl_tab_sample: perform greedy search before performing basis reduction
While basis reduction is very useful on difficult problems, it is
overkill on easy problems. In fact, the basis reduction computation

This may happen in particular during the affine hull computation
when only a few sample points have been found so far. If these

affine hull may have coefficients with larger values still.
Perform a greedy search before computing a reduced basis.

isl_union_set_compute_schedule: ensure carry_dependences makes progress
If solve_lp is unable to find a solution, then compute_schedule_wcc
calls carry_dependences to carry as many dependences as possible.
However, the reason that solve_lp was unable to find a solution
may be due to proximity dependences. In particular, if there are
an infinite number of dependences with the same starting or ending
itereration, then the way proximity dependences are currently handled
may force some of the schedule coefficients to be zero based solely
on those proximity dependences.
carry_dependences may then fail to carry any (validity) dependences
simply because there are no validity dependences.
More generally, it may produce a non-trivial solution on only some
of the nodes. This may result in a number of schedule rows (infinite
in the worst case) that is larger than the maximum computed in
compute_max_row, leading to out-of-bounds accesses.
We therefore check that the schedule row computed by carry_dependences
is non-trivial on all the nodes where it should be non-trivial.
If not, we try again on each dependence graph component separately
or fail if there is only one component.
Note that this commit does not fix the problem that the presence
of proximity dependences may eliminate some valid solutions,
but it should solve the out-of-bounds accesses.

reimplement isl_stream_read_aff in terms of isl_stream_read_multi_aff
Reading an isl_aff is essentially a special case of reading an isl_multi_aff.
We therefore do not need any special code for reading an isl_aff, but can
instead read it as an isl_multi_aff and then extract out the isl_aff.

isl_stream_read_multi_aff: read tuples directly
The original code would call isl_stream_read_pw_multi_aff, which in
turn first parsed the input as a map. Not only does this lead to
needless, potentially expensive, conversions, it also makes it difficult
to parse rational expressions.

isl_input.c: change tuple parsing
Instead of immediately updating an isl_map, we first collect the
information in an isl_multi_pw_aff and then update the isl_map
based on this information.
This will allow us to reuse the tuple parsing in an improved
isl_stream_read_multi_aff.

isl_multi_*_reset_space_and_domain: call isl_*_reset_domain_space
The original code would call isl_*_reset_space_and_domain,
but the space of the multi_* is clearly different from the space of the *,
so it does not make sense to pass that space to the *.
In case of isl_multi_aff, this does not cause any problems because
isl_aff_reset_space_and_domain ignore the first argument.
However, for an isl_multi_pw_aff, this would cause problems.
Call isl_*_reset_domain_space instead.
