The parser now handles maps that contain rest patterns with
subpatterns (e.g. `{'foo': _, ...var rest}`). Even though this is
invalid Dart, it still makes sense for the parser to handle it so that
we can generate higher quality error messages.
The shared type analyzer now generates an error,
`restPatternWithSubPatternInMap`, if it encounters this error
condition.
