care about TAG_FATAL.

TAG_FATAL represents interpreter closing state and ec->errinfo
contains FIXNUM (eTerminateSignal, etc). If we need to change the
state, then errinfo is also changed because TAG_RAISE assumes that
ec->errinfo contains a Exception object.

Without this patch, TAG_FATAL is ignored and no ec->errinfo change
so that it causes critical issue.
