Tobias Grosser 6a2617b874 ScopLib: Support negated access functions.
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.

Tobias Grosser cd95b77330 Pocc: Fix some bugs in the PoCC optimizer pass
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  - Remove outdated references to a 'FinalRead' statement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.

Tobias Grosser 084d8f7d4c ScopInfo: Store ScopStmt pointer in the domain
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.

Tobias Grosser 3cbe5cfff3 Remove FinalRead
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.

Tobias Grosser 29ee0b14d5 Do not use getNameStr() anymore.
Instead we switch to the recommended getName(). This fixes compilation with
recent versions of LLVM.

Tobias Grosser 626227462d JSONImporter: Fix parameter ids when importing new access functions
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

Tobias Grosser 5d45381294 ScopInfo: Only give away a copy of the access relation.
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.

Tobias Grosser b76f385334 Free isl_ctx and fix several memory leaks
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.

Tobias Grosser d5a7bfc51d ScopInfo: Do not return reference to member variable 'domain'.
Instead of returning a pointer to the domain, we return a new copy of it. This
is safer, as we do not give access to internal objects. It is also not
expensive, as isl will just increment a reference counter.
