sh.h (INIT_CUMULATIVE_ARGS): Replace with an invocation of the function sh_init_cumulative_args. 

sh.h (INIT_CUMULATIVE_ARGS): Replace with an invocation of the function
  sh_init_cumulative_args.
  (INIT_CUMULATIVE_LIBCALL_ARGS): Likewise.
  (INIT_CUMULATIVE_INCOMING_ARGS): Delete.
sh-protos.h: Prototype sh_init_cumulative_args.
sh.c (sh_init_cumulative_args): New function based on the contents of the old
  INIT_CUMULATIVE_ARGS macro but with a heuristic added to determine the setting
  of force_mem when a library function is being called.
