eval_intern.h: refine stack overflow detection
* eval_intern.h (TH_PUSH_TAG, TH_EXEC_TAG): refine stack overflow
detection. chain local tag after setjmp() successed on it, because
calling setjmp() also can overflow the stack.
[ruby-dev:47804] [Bug #9109]
* vm_eval.c (rb_catch_obj): now th->tag points previous tag until
TH_EXEC_TAG().
