Previously, only builtin_unreachable of functions accessing jump table
are handled. For split function where jump table could also target the
builtin_unreachable of other sibling fragments, this constraint will
thwart valid entries after such builtin_unreachable entry, and lead to
incorrect jump table analysis results.

This update extend support for builtin_unreachable in sibling fragment.

Test Plan:
