Fix bug in check for constraint `C1604`. The bug disallows the
`event-variable` in an `event-post-stmt` to be a `coindexed-object`, which
is allowed by the standard. Fix `event-post-stmt` and `event-wait-stmt`
tests so that the type of error that hides other errors are isolated
in one test, leaving one test with only standard conforming
statements. This change in testing makes it possible to check
that an `event-variable` in an `event-post-stmt` that is a
`coindexed-object` is now accepted by the compiler after this bugfix.
