Adds a new isInvisible flag for both FunctionDeclarations and
ClosureDeclarations and sets it if the function or closure declaration
is annotated with @pragma('vm:invisible'). This way, function visibility
is appropriately recorded even if options.emitAnnotations is false.
The bytecode reader checks for the isInvisible flag when reading
FunctionDeclarations and ClosureDeclarations and appropriately
sets the is_visible flag for the Function object accordingly.
