cgraph: Handle BUILT_IN_UNREACHABLE_TRAP like BUILT_IN_UNREACHABLE in more spots [PR106258]
The following testcase ICEs because we still have some spots that
treat BUILT_IN_UNREACHABLE specially but not BUILT_IN_UNREACHABLE_TRAP
the same.

* cgraph.cc (cgraph_edge::redirect_call_stmt_to_callee,
cgraph_update_edges_for_call_stmt_node, cgraph_node::verify_node):
Handle BUILT_IN_UNREACHABLE_TRAP like BUILT_IN_UNREACHABLE.
* cgraphclones.cc (cgraph_node::create_clone): Likewise.
* g++.dg/ipa/pr106258.C: New test.
