eval_intern.h: make TH_PUSH_TAG() initialize rb_vm_tag::tag with Qundef
* eval_intern.h (TH_PUSH_TAG): Initialize struct rb_vm_tag::tag with
Qundef rather than 0 which is equal to Qfalse. Since Kernel#throw(obj)
searches a tag with rb_vm_tag::tag == obj, throw(false) can
accidentally find an unrelated tag which is not created by
Kernel#catch. [ruby-core:77229] [Bug #12743]
* test/ruby/test_exception.rb (test_throw_false): Add a test case for
this.
