Adds @skipIfPlatform and @skipUnlessPlatform decorators which will skip if / unless the target platform is in the provided platform list. Test Plan: ninja check-lldb shows no regressions. When running cross platform, tests which cannot run on the target platform are skipped. Differential Revision: http://reviews.llvm.org/D8665 llvm-svn: 233547
