This episode\nfinds us removing references to ArtMethod/ArtField/mirror.\n\nOne aspect of this change that I would like to call out specfically\nis that the utils versions of the \"Pretty*\" functions all were written\nto accept nullptr as an argument.  I have split these functions up as\nfollows:\n1) an instance method, such as PrettyClass that obviously requires\nthis !\u003d nullptr.\n2) a static method, that behaves the same way as the util method, but\ncalls the instance method if p !\u003d nullptr.\nThis requires using a full class qualifier for the static methods,\nwhich isn\u0027t exactly beautiful.  I have tried to remove as many cases\nas possible where it was clear p !\u003d nullptr.\n\nBug: 22322814\nTest: test-art-host\nChange-Id: I21adee3614aa697aa580cd1b86b72d9206e1cb24\n"
