This doesn't attempt to move every decorator. The reason for this is that it requires touching every single test file to import decorators.py. I would like to do this in a followup patch, but in the interest of keeping the patches as bite-sized as possible, I've only attempted to move the underlying common decorators first. A few tests call these directly, so those tests are updated as part of this patch. llvm-svn: 259807
