9a44b97913 Revert "CodeGeneration: Implement ceild/floord exactly as CLooG does" 
I think I did not get the implementation right. As the current implementation
works well, we will just stick with it for now.

0ac9214c2f Recommit "CodeGen: Maintain a valid CFG during code generation" 
When I first tried to commit this patch, the builder pointed after generation
of a loop still into the loop body. This means that code that was supposed to
be generated after the loop was generated right into the loop body. We fixed
this by pointing the builder to the BB after the loop, as soon as code
generation of the loop body itself is finished.

0b6c613a10 CodeGen: Maintain a valid CFG during code generation 
Before this change we built the CFG such that it was only valid after code was
fully generated. During code generation itself, it was often incomplete. After
this change always maintain a valid CFG. This will later allow us to use the
SCEVExpander during code generation. This is the first step to get rid of the
independent blocks pass.

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.

update is utils/checkout_cloog.sh.
