Clean up XFAILed test cases We had a set of test cases that have been incomplete and XFAILED. This patch completes a couple of the interesting ones and removes the ones which seem redundant or not sufficiently reduced to be useful. llvm-svn: 211670

Drop all constant scheduling dimensions Schedule dimensions that have the same constant value accross all statements do not carry any information, but due to the increased dimensionality of the schedule cost compile time.

Introduce reduction types This change is particularly useful in the code generation as we need to know which binary operator/identity element we need to combine/initialize the privatization locations. + Print the reduction type for each memory access + Adjusted the test cases to comply with the new output format and to test for the right reduction type llvm-svn: 212126
