Tobias Grosser 637bd63123 Move polly options into separate option category
Use the new cl::OptionCategory support to move the Polly options into a separate
option category. The aim is to hide most options and show by default only the
options a user needs to influence '-O3 -polly'. The available options probably
need some care, but here is the current status:

Polly Options:
Configure the polly loop optimizer

  -enable-polly-openmp              - Generate OpenMP parallel code
  -polly                            - Enable the polly optimizer (only at -O3)
  -polly-no-tiling                  - Disable tiling in the scheduler
  -polly-only-func=<function-name>  - Only run on a single function
  -polly-report                     - Print information about the activities
                                      of Polly
  -polly-vectorizer                 - Select the vectorization strategy
    =none                           -   No Vectorization
    =polly                          -   Polly internal vectorizer
    =unroll-only                    -   Only grouped unroll the vectorize
                                        candidate loops
    =bb                             -   The Basic Block vectorizer driven by
                                        Polly

Polly - Polyhedral optimizations for LLVM
-----------------------------------------
http://polly.llvm.org/

Polly uses a mathematical representation, the polyhedral model, to represent and
transform loops and other control flow structures. Using an abstract
representation it is possible to reason about transformations in a more general
way and to use highly optimized linear programming libraries to figure out the
optimal loop structure. These transformations can be used to do constant
propagation through arrays, remove dead loop iterations, optimize loops for
cache locality, optimize arrays, apply advanced automatic parallelization, drive
vectorization, or they can be used to do software pipelining.
