expectedFailureWindows is equivalent to using the general expectedFailureAll decorator with oslist="windows". Additionally, by moving towards these common decorators we can solve the issue of having to support decorators that can be called with or without arguments. Once all decorators are always called with arguments, and this is enforced by design (because you can't specify the condition you're decorating for without passing an argument) the implementation of the decorators can become much simpler Differential Revision: http://reviews.llvm.org/D16936 llvm-svn: 260134
