Add preliminary implementation for GPGPU code generation.
...
Translate the selected parallel loop body into a ptx string and run it
with cuda driver API. We limit this preliminary implementation to
target the following special test cases:
- Support only 2-dimensional parallel loops with or without only one
innermost non-parallel loop.
- Support write memory access to only one array in a SCoP.

CLooG: Do not take into account the context
...
CLooG and the CLooG based code generation does not yet correctly derive the
types of the expressions, but just uses i64 for everything. This is incorrect,
but works normally pretty well. However, the recent change of adding parameter
bounds to the context made CLooG generate expressions that contain a lot of very
large integers that possibly don't fit into an i64. This broke the code
generation for several benchmarks.
To get the CLooG based code generation working again, we just don't take into
account any constraints in the context. This brings us back to the theoretical
incorrect, but in practice generally correct code.
The next step will be the isl based code generation. Here we will derive
automatically correct types.

Grouped unrolling means that we unroll a loop such that the different instances

vectorization should be performed.

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.

We create a new file LoopGenerators that provides utility classes for the

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.

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.

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.
