Tobias Grosser 89339067b0 CodeGen: Allow function parameters to be rewritten in getNewValue() 
When deriving new values for the statements of a SCoP, we assumed that parameter
values are constant within the SCoP and consquently do not need to be rewritten.
For OpenMP code generation this assumption is wrong, as such values are not
available in the OpenMP subfunction and consequently also may need to be
rewritten.

Committed with some changes.

Tobias Grosser f74a4cd3dd CodeGen: Extract the LLVM-IR generaction of scalar and OpenMP loops.

Tobias Grosser d6adda3071 CodeGen: Full support for isl_pw expressions in modified access functions. 
This also adds support for modifiable write accesses (until now only read
accesses where supported). We currently do not derive an exact type for the
expression, but assume that i64 is good enough. This will be improved in future
patches.

Tobias Grosser 0acfcdbe7b 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

Tobias Grosser 3ec2abc5fb 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.

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.
