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.

This update includes a couple more coalescing changes as well as a large
number of isl-internal code cleanups (dead assigments, ...).

This update brings mostly interface cleanups, but also fixes two bugs in
imath (a memory leak, some undefined behavior).

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.
