* tree-tailcall.cc (single_non_eh_succ_edge): New function.
(independent_of_stmt_p): Use single_non_eh_succ_edge (bb)->dest
instead of single_succ (bb).
(empty_eh_cleanup): New function.
(find_tail_calls): Diagnose throwing of exceptions which do not
propagate only if there are no EDGE_EH successor edges. If there are
and the call is musttail, use empty_eh_cleanup to find if the cleanup
is not empty. If not or the call is not musttail, use different
diagnostics. Set is_noreturn even if there are successor edges. Use
single_non_eh_succ_edge (abb) instead of single_succ_edge (abb). Punt
on internal noreturn calls.
(decrease_profile): Don't assert 0 or 1 successor edges.
(eliminate_tail_call): Use
single_non_eh_succ_edge (gsi_bb (t->call_gsi)) instead of
single_succ_edge (gsi_bb (t->call_gsi)).

single succ edge which is EDGE_EH for noreturn musttail calls.
