Serhiy Storchaka efcd65cd84 gh-122313: Clean up deep recursion guarding code in the compiler (GH-122640) ...

Add ENTER_RECURSIVE and LEAVE_RECURSIVE macros in ast.c, ast_opt.c and
symtable.c. Remove VISIT_QUIT macro in symtable.c.

The current recursion depth counter only needs to be updated during
normal execution -- all functions should just return an error code
if an error occurs.
