Jacob Richman 88eb557b65 Fix warnings_checker.dart handling of multitests
Update all tests

Support //# multitests for better dartfmt compatibility and fewer multitest false positives

All files under tests were manually updated with

find . -iregex '.*\.dart$' -print0 | xargs -0 perl -pi -e 's/(\S\s+)\/\/\/ /$1\/\/# /'

For now both old and new styles are allowed to accommodate CO19 tests.
