This tripped me up the other day when grepping for an error message. Thanks to ikonst's --update-data improvements, very easy to fix everywhere.

Feel like it's better to change all these to "cannot" in the place where we generate the message; "can't" is a little too informal.

A handful of errors remain:

FAILED mypy/test/testsemanal.py::SemAnalSuite::semanal-statements.test::testDelMultipleThingsInvalid
FAILED mypy/test/testsemanal.py::SemAnalErrorSuite::semanal-errors.test::testInvalidLvalues10
FAILED mypy/test/testsemanal.py::SemAnalErrorSuite::semanal-errors.test::testInvalidLvalues11
FAILED mypy/test/testtransform.py::TransformSuite::semanal-statements.test::testDelMultipleThingsInvalid

Can we merge this? I think it'll be nice to collapse some [out]s into inline comments once it's done.

If @hauntsaninja is too busy to finish this PR, feel free to create an alternative PR finishing this one, and I'll take a look.
