Tobias Grosser d1e33e7061 ScopDetection: Only detect scops that have at least one read and one write
Scops that only read seem generally uninteresting and scops that only write are
most likely initializations where there is also little to optimize.  To not
waste compile time we bail early.

Tobias Grosser e7e33ba13a Always pipe in test files
In Polly we used to have a mix of test cases, some that used 'opt %s' and others
that used 'opt < %s'. We now change all to use 'opt < %s'. Piping in test files
is preferable as it does prevent temporary files to be written to disk. This
brings us in line with what is usus in LLVM.

Johannes Doerfert c3958b214c Added option for n-dimensional rectangular tiling
+ CL-option --polly-tile-sizes=<int,...,int>
  The i'th value is used as a tile size for dimension i, if
  there is no i'th value, the value of --polly-default-tile-size is
  used

+ CL-option --polly-default-tile-size=int
  Used if no tile size is given for a dimension i

+ 3 Simple testcases
