Add a content keyword to file_test, `[[@0xAB]]`, that expands to the code unit 0xAB, and use that instead of putting raw malformed code units in test files. Instead of printing the raw input bytes in snippets in diagnostics, replace non-printable characters with <AB> in the output, being careful to still compute the location of the caret and underscore properly.
