This has shown better results for 2mm, 3mm and a couple of other benchmarks.
After this we show consistenly better results as PoCC with maxfuse. We need
to see if PoCC can also give better results with another fusion strategy.

Scheduler: Simplify dependences by default (only isl)
...
This speeds up the scheduler by orders of magnitude and in addition yields often
to a better schedule.
With this we can compile all polybench kernels with less than 5x compile time
overhead. In general the overhead is even less than 2-3x. This is still with
running a lot of redundant passes and no compile time tuning at all. There are
several obvious areas where we can improve here further.
There are also two test cases where we cannot find a schedule any more (cholesky
and another). I will look into them later on.
With this we have a very solid base line from which we can start to optimize
further.

Scheduler: Try to maximize the band depth
...
Previously the scheduler was splitting bands at the level at which it detected
that the splitting of the band is necessary. This may introduce an additional
level of bands, that can be avoided by backtracking and splitting on a higher
level. Additional splits reduce the number of loops that can be tiled, such that
avoiding splits and maximizing the band depth seems preferable.
As a first data point we looked at 2mm and 3mm from the polybench test suite.
For both maximizing the tilable bands results in a significant (5-10x)
performance improvement.
This patch enables the isl scheduler option to maximize the band depth.

Scheduler: Set maximal constant term
...
If larger coefficients appear as part of the input dependences, the schedule
calculation can take a very long time. We observed that the main overhead in
this calculation is due to optimizing the constant coefficients. They are
misused to increase locality by merging several unrelated dimensions into a
single dimension. This unwanted optimization increases the complexity of the
generated code and furthermore slows it down.
We use a new isl scheduler option to bound the values in the constant dimension
by a user defined value (20 in our case). If the right value is choosen, costly
overoptimization is prevented.
This solution works, but requires a specific (here almost randomly choosen)
value by which the constants are bound. For the moment, this is our best
solution, but we hope to to find a more generic one later on.
After these patch the extremly long compile time for simple kernels like 2mm or
3mm is reduced to a reasonable amount of time (Not more than a couple of seconds
even in debug mode).

The SCEV Validator is used to check if the bound of a loop can be translated

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.

Polly adds, after it is loaded into opt or clang, its passes to the default set

clang -Xclang -load -Xclang lib/LLVMPolly.so -O3 program.c
The same should work for dragonegg powered gfortran, g++, ... or any other tool
that uses the PassManagerBuilder.
Warning: Even though using Polly became with this commit extremly easy, Polly
is still Pre-Alpha Quality. This means in most cases it will rather
destroy the world than doing anything positive. ;-)

ScopInfo: Remove adhoc comparision of affine expressions
...
Until today, we compared two affine expressions by defining two maps describing
them, creating an union of those maps, adding constraints that do the comparison
and projecting out unneeded dimensions.
This was simplified to using the isl_pw_aff representation of the affine
expressions and using the relevant isl functions to compare them.
