This change adds line position tests for several yyerror calls in the typechecker that are currently not tested in any way. Untested yyerror calls were found by replacing them with yerrorl(src.NoXPos, ...) (thus destroying position information in the error), and then running the test suite. No failures means no test coverage for the relevant yyerror call.
