re PR debug/50006 (ICE in in connect_traces, at dwarf2cfi.c:2677)
PR middle-end/50006
* explow.c (allocate_dynamic_stack_space): Move suppress_reg_args_size
setting out to include allocate_stack named pattern as well.
* builtins.c (expand_builtin_apply): Add ARG_SIZE 0 note.
* stmt.c (expand_stack_restore): Likewise.
