Raghesh Aloor a71989c94e Memaccess: Using isl_map_dim_max 
Use isl_map_dim_max to extract the details of the changed
access relation. Only constant access functions are supported
now.

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 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.

Tobias Grosser f53388034d Adapt to introduction of isl_space 
Polly should now be compiled with CLooG 0c252c88946b27b7b61a1a8d8fd7f94d2461dbfd
and isl 56b7d238929980e62218525b4b3be121af386edf. The most convenient way to
update is utils/checkout_cloog.sh.

Tobias Grosser 8ae9aca5cc CodeGen: Improve naming of copied basic blocks 
It may happen that we generate the code of a basic block from the original
scop is code generated several times. The new naming scheme reduces confusing
that earlier appeared as the version numbers of the new basic blocks could
have been interpreted as part of the name of the original basic block.

Tobias Grosser c532f12965 Fix crashes due to unaligned parameters 
Due to the recent introduction of isl_id, parameters need now always to be
aligned. This was not yet taken care of in the code path of vectorization and
dependence analysis.

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.

Raghesh Aloor 62b13120ee Memaccess: Codegeneration for a simple access function change 
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.
