This move the test of the "native" syntax, support by the CFE, to
a separate test. The test (expecting the syntax to _not_ be supported)
fails on the CFE but that has nothing to with the records/patterns
features which the remaining tests in syntax_test.dart require.

New language features made `futureOr(null) = 1` a syntactically
correct pattern assignment, so it should not be expected to cause a
syntax error. This CL changes that test case such that it is still an
assignment to a syntactically correct function invocation, but not a
correct pattern assignment (so it's again a syntax error).
Added more tests with similar properties: The 3.0 grammar causes some
test cases to be wrong, and this CL makes changes such that they will
continue to test "the same thing" as far as possible in the new
language.
