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`).
