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. ;-)

- Use __isl_give and __isl_take
- Convert variables to start with Uppercase letter
- Only assign the 'domain' after it is fully constructed
- Only name it after it is fully constructed

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.

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.

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.

Polly adds, after it is loaded into opt or clang, its passes to the default set
of -O3 passes. This means optimizing a program with clang and Polly becomes as
simple as executing.
clang -Xclang -load -Xclang lib/LLVMPolly.so -O3 program.c
The same should work for dragonegg powered gfortran, g++, ... or any other tool
that uses the PassManagerBuilder.
Warning: Even though using Polly became with this commit extremly easy, Polly
is still Pre-Alpha Quality. This means in most cases it will rather
destroy the world than doing anything positive. ;-)

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.
