[Polly] Update isl to isl-0.27-78-gfc484e00 (#180377)
Update isl to include
https://repo.or.cz/isl.git/commit/fc484e004200964f8f18249de1f510393ec924a9
which fixes #180000.

The isl update also fixes #34710 which had the same cause but with an
empty access domain (#180000 has an empty statement domain). Thus we
also revert 163cacb46960be4dd0d8562737bbf0ea97cb14ad which now only adds
unnecessary overhead.

A regression test has been added to isl which is why we do not add a
test in Polly.

Fixes: #180000

Thanks @skimo-openhub for the fix and @thapgua for the bugreport.

The libraries in this directory are mirrored from external projects.

Patches to them should first be contributed upstream and then return to Polly
as normal (re)imports of these updated libraries.

We currently have the following external libraries.

# isl
License: MIT-STYLE
Details: isl/LICENSE

# imath
License: MIT-STYLE
Details: isl/imath/LICENSE

To update these libraries run 'autoreconf -i && ./configure && make dist' in
the isl git directory and move the resulting files into lib/External/isl.
Alternatively, run the update-isl.sh script.
