Tobias Grosser ce27773a8e Update isl to isl-0.19-173-g77fe2538
Besides other changes, this update introduces functions to translate a
maps and sets into lists of their elements. These lists are useful as
we can define iterators for lists, which allow us to replace many uses
of foreach.

Besides normal updates this change also contains a bug-fix to in
isl_coalesce which broke the AOSP buildbot. Thanks to Michael Kruse for
reporting this bug and Sven Verdoolage for fixing this bug.

Tobias Grosser fa8079d0dc Update isl to isl-0.18-1047-g4a20ef8
This update:

  - Removes several deprecated functions (e.g., isl_band).
  - Improves the pretty-printing of sets by detecting modulos and "false"
    equalities.
  - Minor improvements to coalescing and increased robustness of the isl
    scheduler.

This update does not yet include isl commit isl-0.18-90-gd00cb45
(isl_pw_*_alloc: add missing check for compatible spaces, Wed Sep 6 12:18:04
2017 +0200), as this additional check is too tight and unfortunately causes
two test case failures in Polly. A patch has been submitted to isl and will be
included in the next isl update for Polly.

Tobias Grosser 52a25237d8 Import isl(+imath) as an external library into Polly
With this patch Polly is always GPL-free (no dependency on GMP any more). As a
result, building and distributing Polly will be easier. Furthermore, there is no
need to tightly coordinate isl and Polly releases anymore.

We import isl b3e0fa7a05d as well as imath 4d707e5ef2. These are the git
versions Polly currently was tested with when using utils/checkout_isl.sh. The
imported libraries are both MIT-style licensed.

We build isl and imath with -fvisibility=hidden to avoid clashes in case other
projects (such as gcc) use conflicting versions of isl. The use of imath can
temporarily reduce compile-time performance of Polly. We will work on
performance tuning in tree.

Patches to isl should be contributed first to the main isl repository and can
then later be reimported to Polly.

This patch is also a prerequisite for the upcoming isl C++ interface.
