Fix PR3766, a really nasty silent miscompilation case where we emitted
a warning and then threw away the AST. While I'm in there, tighten up the
code to actually reject completely bogus cases (sending a message to a
struct). We still allow sending a message to an int, which doesn't make
sense but GCC allows it and is easy to support.
