[Bug translator/6908] New: "return" without value in "unknown" type function causes an error.

I found the following mysterious error message.
---
$ stap -e 'function func:unknown() { return }' -p2
parse error: expected 'string' or 'long'
	saw: identifier 'unknown' at <input>:1:15
1 parse error(s).
Pass 1: parse failed.  Try again with more '-v' (verbose) options.
---
I think no one can expect any *unknown* value...

We don't have a return-value-less "return" statement, since that
would require the parser to understand types.  This particular
error message is by the way from the use of the "unknown" keyword
in the first place, which is not actually a keyword.
