Update isl to ensure 'extern "C" {' is available

Older isl versions did not properly guard all function declarations for the
use in C++. Specifically, the isl/val_gmp.h header was not properly guarded.
This patch ensures we have the proper guards in place and do not accidentally
link to name-mangled C++ versions of those functions that are not available in
libisl.so.

Update CLooG and some test cases

This is necessary to avoid test failures in the CLooG test suite due to the
recent isl update.

We also need to update two polly test cases which rely on a certain order in the
textual description that isl chooses for its sets and maps. Changes here are not
often, but we should probably switch to a check that verifies such maps are
semantically equivalent instead of represented identically.

Ported scoplib to use isl_val * instead of isl_int

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.

ScheduleOptimizer: Fix prevectorization.

In case we are at the innermost band, we try to prepare for vectorization. This
means, we look for the innermost parallel loop and strip mine this loop to the
innermost level using a strip-mine factor corresponding to the number of vector
iterations.

For whatever reason, the code that implemented this feature was broken. We now
added a comment, a test case and obviously also the right code.
