This CL changes the specification parser grammar to support a switch
expression that has zero cases (this is a missing update, the feature
specification already has it). It also changes several language tests
such that they expect a 'syntax error' rather than a 'compile-time
error'. This makes no difference for any tool except the specification
parser, for which it is needed (in general, a test that is expected
to have a compile-time error will parse just fine, so we need a
separate test outcome expectation for syntax errors).
