Issue Description:

Parser::parseDeclOperatorImpl() accepts code like this:

prefix operator <<< :
func foo() {}

That is, there is a colon but no list of identifiers after it.

The parser should probably should reject this code, but if anyone has written this anywhere, that would break source compatibility.
