Do not fail if a command line argument is given more than once
...
For boolean flags in Polly there is no problem if they are given more than once.
Hence, we can allow it to not fail for build systems that (acciently) add flags
several times.
This fixes: PR12278

Don't allow pointer types in affine expressions
...
We currently do not support pointer types in affine expressions. Hence, we
disallow in the SCoP detection. Later we may decide to add support for them.

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.

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).
