Johannes Doerfert f1906138b4 Model statement wise reduction dependences
+ Collect reduction dependences
+ Introduced TYPE_RED in Dependences.h which can be used to obtain the
  reduction dependences
+ Used TYPE_RED to prevent parallelization while we do not have a privatizing
  code generation
+ Relax the dependences for non-parallel code generation
+ Add privatization dependences to ensure correctness
+ 12 Test cases to check for reduction and privatization dependences

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

Saleem Abdulrasool e653622b98 polly: update for LLVM API change
SVN r209103 removed the OwningPtr variant of the MemoryBuffer APIs.  Switch to
the equivalent std::unique_ptr versions.  This should clear up the build bots.

Chandler Carruth 95fef9446c [Modules] Fix potential ODR violations by sinking the DEBUG_TYPE
definition below all of the header #include lines, Polly edition.

If you want to know more details about this, you can see the recent
commits to Debug.h in LLVM. This is just the Polly segment of a cleanup
I'm doing globally for this macro.

Chandler Carruth 1fc97224af Fix more build errors in Polly after r206310. David caught one of these
in r206312, but others don't seem to show up on build bots? Unsure of
why, they showed up for me.

Tobias Grosser 64b95123ef Delete trivial PHI nodes (aka stack slot sharing)
During code preperation trivial PHI nodes (mainly introduced by lcssa) are
deleted to decrease the number of introduced allocas (==> dependences). However
simply replacing them by their only incoming value would cause the independent
block pass to introduce new allocas. To prevent this we try to share stack slots
during code preperarion, hence to reuse a already created alloca 'to demote' the
trivial PHI node. This works if we know that the value stored in this alloca
will be the incoming value of the trivial PHI at the end of the predecessor
block of this trivial PHI.
