3fb4992221 ScopDetection: Add new SCEV Validator 
The SCEV Validator is used to check if the bound of a loop can be translated
into a polyhedral constraint. The new validator is more general as the check
used previously and e.g. allows bounds like 'smax 1, %a'. At the moment, we
only allow signed comparisons. Also, the new validator is only used to verify
loop bounds. Memory accesses are still handled by the old validator.

3638ef8fe1 PoCC: Fix bugs when executing PoCC 
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. ;-)

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.

The tool is called checkout_cloog.sh. We also update the get_started
documentation to include this tool. An older unfinished tool called
'get_cloog.sh' is removed to avoid confusion.
