This got accidentally dropped in r264283.
Also, drop the wwwfiles from the removal list. This is not needed any more as
we now explicitly list the directories that should be formatted.

Refactor all ISL-related cmake build instructions into its own
CMakeLists.txt and build as a separate library.
This is useful to apply ISL-related build flags to ISL only and not to
Polly's files. Also, it the separation of both projects becomes clearer.
Proposed name of the library is Polly_isl. It is not "isl" to avoid
mix-up with potentially installed libisl.{a|so}.
Tested configurations:
- Windows with cmake 3.2
- Ubuntu with cmake 3.0.2
- Ubuntu with cmake 3.0.2 BUILD_SHARED_LIBS on
- Ubuntu with cmake 2.8.12.2 (LLVM minimum version)
- Ubuntu out-of-LLVM-tree

Summary:
Make clang-format run on each file independently using
add_custom_format (instead using a shell script in utils/). The targets
polly-{update|check}-format depend on these.
The primary motivation is to make them work on Windows, but also
improves them generally:
- Each file update/check can run in parallel (Although they do not take
long to run anyway)
- Implicit dependency on clang-format, so it recompiles if necessary
- polly-check-format shows the formatting difference if failing

When compiling Polly without LLVM sources but with system-installed
LLVM, the build process would not honor the LLVM_ENABLE_ASSERTIONS
setting LLVM was compiled with, but effectively assume that it is
switched off when compiling. During unit-tests llvm-lit would still
query the LLVM_ENABLE_ASSERTIONS flag and enable tests which require
assertions. Even if enabled for LLVM, Polly does not output its debug
info and statistics in this this mode such that 7 tests fail.
To fix, we query llvm-config --assertion-mode and if on, enable
assertions as HandleLLVMOptions.cmake would do.
We cannot reliably use HandleLLVMOptions.cmake itself as the host's
LLVM build might have been built using automake and distributions
change file locations (e.g. Debian to
/usr/share/llvm-${VERSION}/cmake/HandleLLVMOptions.cmake).

Put all Polly targets into a single "Polly" category (i.e.
solution folder). Previously there was no recognizable scheme and most
categories contained just one or two targets or targets didn't belong
to any category.

Remove the polly_headers_do_not_build project. Visual Studio is capable
of finding the headers itself, although they are not listed explicitly.
For explicit listing, the headers should be added to the relevant
target.

There were two issues:
* ISL's configure generates include/isl/stdint.h, not isl/stdint.h as
assumed. This is also changed in the CMake build.
* Need to pass --with-int=imath to ISL's configure; the default is gmp.
Polly's configure has been regenerated due to changing configure.ac

Currently the Polly repository contains the ISL sources with bogus
isl_config.h and gitversion.h. This is problematic. In this state a
macro
#define __attribute__(x)
becomes active in the source, leading to various problems e.g. when
included before system header files. This patch will instead generate
the two files specific to the host system at configure-time.
For CMake, we replicate the tests that ISL's configure performs using
try_compile(). In autotools build, we just invoke ISL's configure to
generate the two files. This consequently required regenerating
autoconf/configure.
'make dist' distributions of ISL contain a file GIT_HEAD_ID which
contains the version the distribution is derived from. The repository
files themselves do not contain such a hint. In a later commit we will
replace the isl directory by the contents of such a .tar.gz. It does
not contain the files imdrover.c iprime.c pi.c and rsamath.c currently
compiled into Polly, but not used and therefore are removed by this
patch.
In the long term we plan to generate a dedicated library for ISL instead
of adding its files to Polly.
This also does not yet include the switch to small-integer optimized ISL
nor enabling C99 mode required for the former. Those will come as well
in separate patches.

We do not have buildbots or anything that tests this functionality, hence it
most likely bitrots. People interested to use this functionality can always
recover it from svn history.

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.

This commit drops the Cloog support for Polly. The scripts and
documentation are changed to only use isl as prerequisity. In the code
all Cloog specific parts have been removed and all relevant tests have
been ported to the isl backend when it was created.

Arcanist (arc) will now always run linters before uploading any new
commit to Phabricator. All errors/warnings (or their absence) will be
shown in the web interface together with a explanation by the commiter
(arcanist will ask the commiter if the build was not clean).
The linters include:
- clang-format
- spelling check
- permissions check (aka. chmod)
- filename check
- merge conflict marker check
Note, that their scope is sometimes limited (see .arclint for
details).
This commit also fixes all errors and warnings these linters reported,
namely:
- spelling mistakes and typos
- executable permissions for various text files

We only supported a very old version of OpenScop that was entirely different
to what OpenScop is today. To not confuse people, we remove this old and
unusable support. If anyone is interested to add OpenScop support back in,
the relevant patches are available in version control.

Translate the selected parallel loop body into a ptx string and run it with the
cuda driver API. We limit this preliminary implementation to target the
following special test cases:
- Support only 2-dimensional parallel loops with or without only one innermost
non-parallel loop.
- Support write memory access to only one array in a SCoP.
The patch was committed with smaller changes to the build system:
There is now a flag to enable gpu code generation explictly. This was required
as we need the llvm.codegen() patch applied on the llvm sources, to compile this
feature correctly. Also, enabling gpu code generation does not require cuda.
This requirement was removed to allow 'make polly-test' runs, even without an
installed cuda runtime.

The Apple linker fails by default, if some function calls can not be resolved at
link time. However, all functions that are part of LLVM itself will not be
linked into Polly, but will be provided by the compiler that Polly is loaded
into. Hence, during linking we need to ignore failures due to unresolved
function calls.
