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

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.

isl_union_map_sample: don't return NULL on empty input
Throughout isl, NULL is used to mark an error return, so we shouldn't
return NULL simply because the input is empty. Instead, we now return
an empty basic map living in a fairly arbitrary space, but that shouldn't
be a problem.

isl_basic_set_factorizer: make sure group information gets updated
We lazily keep track of which group a column belongs to.
The actual construction of the factors assumes the groups have been
updated, however, so we need to make sure that the group of each
column eventually gets updated.
