Tobias Grosser a187964bac Support non-affine access functions in Polly.
In case we can not analyze an access function, we do not discard the SCoP, but
assume conservatively that all memory accesses that can be derived from our base
pointer may be accessed.

Tobias Grosser 4dca439cfc Register Passes: Use -polly-optimizer=(isl|pocc) to switch optimizers
This replaces the old option -polly-use-pocc. Also call the passes uniformly
-polly-opt-pocc and -polly-opt-isl.

Tobias Grosser 8f99c167cd ScopInfo: Use names of simple parameters to name the isl parameter dimensions.
Parameters can be complex SCEV expressions, but they can also be single scalar
values. If a parameters is such a simple scalar value and the value is named,
use this name to name the isl parameter dimensions.

Tobias Grosser 60b54f19e6 Detect Parameters directly on the SCEV.
Instead of using TempScop to find parameters, we detect them directly
on the SCEV. This allows us to remove the TempScop parameter detection
in a subsequent commit.

This fixes a bug reported by Marcello Maggioni <hayarms@gmail.com>

Tobias Grosser 8ae9aca5cc CodeGen: Improve naming of copied basic blocks
It may happen that we generate the code of a basic block from the original
scop is code generated several times. The new naming scheme reduces confusing
that earlier appeared as the version numbers of the new basic blocks could
have been interpreted as part of the name of the original basic block.

Tobias Grosser c532f12965 Fix crashes due to unaligned parameters
Due to the recent introduction of isl_id, parameters need now always to be

Tobias Grosser 604c981f40 Temporarily remove reduction support and interchange pass
I am planning to eliminate the TempScopInfo pass. To simplify this I remove
some features that may later be added to the ScopInfo pass.

The interchange pass is currently strongly tested and furthermore ment to be
replaced by the general scheduling optimizer. Reductions itself can later
be added easily.
