re PR debug/55094 (ICE in maybe_record_trace_start, at dwarf2cfi.c:2224)

PR middle-end/55094
* builtins.c (expand_builtin_trap): Add REG_ARGS_SIZE note
on the trap insn for !ACCUMULATE_OUTGOING_ARGS.
* cfgcleanup.c (outgoing_edges_match): Don't look at debug insns
on the first old_insns_match_p call.  For !ACCUMULATE_OUTGOING_ARGS
fail if the last real insn doesn't have REG_ARGS_SIZE note.

* gcc.dg/pr55094.c: New test.
