Opt multitests out of formatting in ffi/.

The new formatter supports opting a region of code out from being
formatted. I'm applying this marker to all of the multitests since
those tests are often very sensitive to formatting and easily broken.
This way, anyone touching a multitest (including me when I reformat
the tests) doesn't have to remember to not run the formatter on it.
