No need to pretend anymore that we do not update the LLVM-IR.

As we do not delete the SCoP, there is no need to remove it from the SCoP
detection.

The isl based routines implement a new interpretation of the Pluto algorithm
new interpretation. This patch requires a recent version of isl to be installed.

If we only want to optimize a single function, we should extract this function
into a separate .ll file. This simplifies the code.

Instead of deleting the old code, keep it on the side in an if-branch. It will
either be deleted by the dead code elimination or we can use it as fallback.

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.

  do not re-generate code for these functions.

Refactor: Move 'isParallelFor' from codegen backend to Dependences analysis, so other passes can also use it.

Use the content of the Polly wiki page[1] to create a new website. I do not yet
plan to officially promote this website, but it is already a solid base that we
can improve and peer review.
