Zachary Turner 7289e43831 Refactor some of the xfail / skip decorators to share logic.
Previously the logic of skipIf and expectedFailure were 99%
the same, but they took different sets of arguments since they
were maintained separately, and had slightly differences in
their behavior.  This makes everything consistent, there is now
only one real implementation, and the previous ones are changed
to use the single master implementation.
