Filter: Ensure that all expressions declared return type
All instructions with a return value (i.e. expressions, ones with non-zero outval, third argument in INST()) should declare their return type. Check that automatically by M4 macros. Set outval of FI_RETURN to 0. The instruction adds one value to stack, but syntactically it is a statement, not an expression. Add fake return type declaration to FI_CALL, otherwise the automatic check would fail builds.
