Erik Ernst 40b6741778 Adds support for syntax error in tests to test.py.
This CL modifies the Dart source used from test.py such that it takes
`syntax error` into account as an expected outcome in test files (so
that we can have `//# 01: syntax error` with a similar meaning as
`//# 01: compile-time error`).

For all tools except the spec_parser, `syntax error` is the same
outcome as `compile-time error`; that is, nobody else will see the
difference.

For the spec_parser, `syntax error` is the outcome where parsing has
failed; `compile-time error` is taken to mean some other compile-time
error, i.e., the spec_parser is expected to _succeed_ when the
expected outcome is `compile-time error`.

Test files in language and language_2 have been adjusted to use the
outcome `syntax error` where appropriate.

The status files in language and language_2 for the spec_parser have
been adjusted such that they fit all the new `syntax error` outcomes
in test files.

Other status files have been adjusted in a few cases where tests were
corrected (because a compile-time error which was clearly not intended
to be a syntax error turned out to be caused by a typo, which means
that the actual compile-time error has never been tested).

The spec grammar Dart.g was adjusted in a few cases, when some bugs
were discovered. In particular, the treatment of Function has been
changed: It is now known by the parser that Function does not take
any type arguments. This makes no difference for developers, because
they cannot declare a type named Function anyway, but it means that
a number of tricky parsing issues were resolved.

Dart.g was also adjusted to allow `qualified` to contain three
identifiers, which is an old bug (preventing things like metadata on
the form `@p.C.myConst`).
