isl_stream_read_map: allow existential quantification over disjunctions
Before, we would only allow existential quantification within a single
disjunct because the existentially quantified variables were being
added directly to a basic map.
Now, we first add extra output variables and project them out at the end.
The disadvantage is that we currently lose any explicit definition of
the existentially quantified variables in the input. Usually, we can
recover them from the constraints that are added when we meet such a
definition, but it does require some extra processing.

isl_tab_basic_map_partial_lexopt: fix up symmetry detection
The symmetry detection of a41dca9 (isl_tab_basic_map_partial_lexopt:
detect and exploit simple symmetries, Mon Dec 13 16:45:44 2010 +0100)
was a bit too eager in that it would also detect symmetries on affine
expressions involving existentially quantified variables.
Those variables are only available in the input and therefore the
mechanism for exploiting symmetries does not work on them, leading
to incorrect results.

Add GDB module that defines an islprint command
Add a python library that is installed next to libisl. GDB will automatically
load it and add a new gdbcommand called "islprint". This command can be used to
prettyprint isl values. It does not install an official pretty printer, as such
a printer will also pretty print stacktraces which may reference values already
freed.
Before:
(gdb) print stride
$1 = (isl_set *) 0x122e6c0
Now also possible:
(gdb) islprint stride
$1 = "{ MemRef_A[1] }"
(gdb) is stride
$1 = "{ MemRef_A[1] }"

reimplement isl_map_partial_lexopt
In case of a map that is a union of more than one basic map,
the old implementation would look for solutions of later basic
maps in those pieces of the domain where earlier basic maps
have no solutions. This could lead to the domain being broken
up into many small pieces, sometimes dramatically so.
The new implementation tries to avoid some of this splintering
by computing solutions for each basic map separately and then
combining the results.
In the reported case, the map was actually single-valued, so
instead we could have also detected this special case and just
returned the input or we could have tried to make the parametric
integer programming integer return a more compact result,
but the new implementation is more general that the first option
and easier than the second option.
