fix(codegen): raise a runtime error when a FUNCTION ends without RETURN
Report the function and its header line, then throw, instead of silently
returning zero. FUNCTION MAIN keeps its implicit result.

RETURNS specifies the result type; omitting it defaults to INTEGER. RETURN supplies a value of that type. If execution reaches ENDFUNCTION without a RETURN, a run-time error is reported and an exception is thrown (the top-level MAIN is exempt). Whole-array results are unsupported. As a compiler extension, `name(arguments)` may also be a complete statement that discards the result. This differs from guide section 8.2, which requires function calls to occur within expressions. Built-in functions support the same form. |
