This fixes reference counting if the schedule optimizer is used.

I am planning to eliminate the TempScopInfo pass. To simplify this I remove
some features that may later be added to the ScopInfo pass.

The interchange pass is currently strongly tested and furthermore ment to be
replaced by the general scheduling optimizer. Reductions itself can later
be added easily.

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.

This simplifies the code quite a bit.

Until today, we compared two affine expressions by defining two maps describing
them, creating an union of those maps, adding constraints that do the comparison
and projecting out unneeded dimensions.

This was simplified to using the isl_pw_aff representation of the affine
expressions and using the relevant isl functions to compare them.

At the moment, we still remove the ids after all data structures are created,
as later passes do not yet support ids. This limitation will be removed later.

Do not use AffFunc to derive the affine expressions, but use isl_pw_aff to
analyze the original SCEV directly. This will allow several simplifications in
follow up patches, with the final goal of removing AffFunc completely.

Support for generating code for an access function change which is
a constant is added.

Code is generated for a simple access function change imported
from JSCOP file. An access of A[i] is changed to A[0]. The code
for A[0] is generated directly without refering to isl function calls.

The changed access relations imported from JSCOP file is shown
as output of -analyze pass.

the inner loop index was not initialized to zero.

This patch reads the change in access functions from
imported JSCOP file. A test case is also added.
