Raghesh Aloor b20b49e3f0 Memaccess: Removing unwanted code 
When the code is moved to IslGenerator class there is no use for
IslPwAffUserInfo.

Tobias Grosser 3cbe5cfff3 Remove FinalRead 
The FinalRead statement represented a virtual read that is executed after the
SCoP. It was used when we verified the correctness of a schedule by checking if
it yields the same FLOW dependences as the original code. This is only works, if
we have a final read that reads all memory at the end of the SCoP.
We now switched to just checking if a schedule does not introduce negative
dependences and also consider WAW WAR dependences. This restricts the schedules
a little bit more, but we do not have any optimizer that would calculate a more
complex schedule. Hence, for now final reads are obsolete.

Tobias Grosser 5c0e7190ff Dependences: Simplify the check if a new scattering is valid. 
We now just check if the new scattering would create non-positive dependences.
This is a lot faster than recalculating dependences (which is especially slow
on tiled code).

works well, we will just stick with it for now.
