Auto merge of #6084 - ebroto:ui_tests_cleanup, r=flip1995

UI tests cleanup `@matthiaskrgr` noticed some `run-pass` annotations in some crash tests that were added in #3922. At that moment they seemed to be necessary to make the tests fail in case of an ICE, but they do not seem to be needed anymore. To test this I forced an ICE in a file with and without annotations, with and without stderr files, and the ICE makes the test fail every time. In addition, I've applied a suggestion from `@ehuss` and `@jyn514` to add `emit=metadata` to the rustc flags for the UI tests. In my machine this improved the run time from ~17 to ~12 seconds. changelog: none
