f317e3ac83 Do not check memory accesses additionally with isValidAffineFunction 
This check was necessary because of the use AffineSCEVIterator in TempScopInfo.
As we removed this use recently it is not necessary any more.

60b54f19e6 Detect Parameters directly on the SCEV. 
Instead of using TempScop to find parameters, we detect them directly
on the SCEV. This allows us to remove the TempScop parameter detection
in a subsequent commit.

This fixes a bug reported by Marcello Maggioni <hayarms@gmail.com>

6be480c4ab ScopInfo: Don't add common parameters during realignment to the context. 
Previously we built a context that contained already all parameter dimensions
from the start. We now build a context without any parameter dimensions and
extend the context as needed. All parameter dimensions are added during final
realignment.

76164677f8 ScopDetection: Use SCEVValidator for memory accesses. 
We currently run the old memory access checker in parallel, as we would
otherwise fail in TempScop because of currently unsupported functions. We will
remove the old memory access checker as soon as TempScop is fixed.

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.
