isl_map_coalesce: be more relaxed about multiple equalities being adjacent
We try to avoid wrapping in a basic map that has multiple equalities
that are adjacent to inequalities in the other basic map, because that
may lead to more complicated constraints.
The original check would, however, also prevent the extension of
one basic map with an other if they happened to lie in a shared
affine subspace. By moving the test for multiple equalities after
the check for extensions, we allow such extensions, while still
preventing undesired wrapping.
We can probably do better by explicitly detecting and exploiting
the shared affine subspace.

None of the constraints are changed in any way, so there shouldn't
be any need to call isl_basic_map_simplify.

isl_map_is_subset: don't compute divs of minuend
The knowns divs of the minuend can be exploited, but only those
of the subtrahend are essential for the implementation.
Since the computation of divs can be expensive and since they
are just thrown away afterwards, it's probably best not to compute
the divs of the minuend explicitly.
In principle, isl_map_subtract could be changed in a similar way,
but there the divs are actually visible in the result, so it may
be worth it to compute them.
