SVN r209103 removed the OwningPtr variant of the MemoryBuffer APIs. Switch to
the equivalent std::unique_ptr versions. This should clear up the build bots.

definition below all of the header #include lines, Polly edition.
If you want to know more details about this, you can see the recent
commits to Debug.h in LLVM. This is just the Polly segment of a cleanup
I'm doing globally for this macro.

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.

1) The isl_int -> isl_val changes are the ones Tobias suggested.
One additional isl_val_free is added (and needed)
2) Three scoplib_vector_free are added, maybe we would need even
more (and matrix_free) but it's hard to place them right.
3) Cleaned the includes (and removed 'extern C')
This fixes the broken compilation for the scoplib import and export.

The module LLVMPolly.so links to that. There is really no reason to build a
large number of mini-libraries here, especially as we do have dependences
between the libraries that are not properly handled and that make linking fail
on darwin.

In case we detect that the schedule the user wants to import is invalid we
refuse it _and_ free the isl_maps containing it.
Another bug found thanks to Rafael.

Use the new cl::OptionCategory support to move the Polly options into a separate
option category. The aim is to hide most options and show by default only the
options a user needs to influence '-O3 -polly'. The available options probably
need some care, but here is the current status:
Polly Options:
Configure the polly loop optimizer
-enable-polly-openmp - Generate OpenMP parallel code
-polly - Enable the polly optimizer (only at -O3)
-polly-no-tiling - Disable tiling in the scheduler
-polly-only-func=<function-name> - Only run on a single function
-polly-report - Print information about the activities
of Polly
-polly-vectorizer - Select the vectorization strategy
=none - No Vectorization
=polly - Polly internal vectorizer
=unroll-only - Only grouped unroll the vectorize
candidate loops
=bb - The Basic Block vectorizer driven by
Polly

After this commit, polly is clang-format clean. This can be tested with
'ninja polly-check-format'. Updates to clang-format may change this, but the
differences will hopefully be both small and general improvements to the
formatting.
We currently have some not very nice formatting for a couple of items, DEBUG()
stmts for example. I believe the benefit of being clang-format clean outweights
the not perfect layout of this code.

Scoplib only supports access functions, but not the more generic
access relations. This commit now also supports access functions
that where not directly expresses as A[sub] with sub = i + 5b,
but with A[sub] with -sub = -i + (-5b).
Test case to come.

This includes:
- The isl_id of the domain of the scattering must be copied from the original
domain
- Remove outdated references to a 'FinalRead' statement
- Print of the Pocc output, if -debug is provided.
- Add line breaks to some error messages.

Store a pointer to each ScopStmt in the isl_id associated with the space of its
domain. This will later allow us to recover the statement during code
generation with isl.

The FinalRead statement represented a virtual read that is executed after the
SCoP. It was used when we verified the correctness of a schedule by checking if
it yields the same FLOW dependences as the original code. This is only works, if
we have a final read that reads all memory at the end of the SCoP.
We now switched to just checking if a schedule does not introduce negative
dependences and also consider WAW WAR dependences. This restricts the schedules
a little bit more, but we do not have any optimizer that would calculate a more
complex schedule. Hence, for now final reads are obsolete.

The new isl_id support for parmeters created problems when importing new
access functions. Even though the parameters had the same names,
they were mapped to different ids and where therefore incompatible.
We copy the ids now from the old parameter dimensions. This fixes the
problem.

These are remainders of the switch to the newer isl version. At the point of
switching I did not test with PoCC support. I should have done. ;-)

Also take the chance and rename access functions to access relations. This is
because we do not only allow plain functions to describe an access, but we
can have any access relation that can be described with linear constraints.

Polly should now be compiled with CLooG 0c252c88946b27b7b61a1a8d8fd7f94d2461dbfd
and isl 56b7d238929980e62218525b4b3be121af386edf. The most convenient way to
update is utils/checkout_cloog.sh.

Because of me not understanding the LLVM pass structure well, I did not find a
good way to allocate isl_ctx and to free it later without getting issues with
reference counting. I now found this place, such that we can free isl_ctx. This
patch also fixes the memory leaks that were ignored beforehand.
