	PR rtl-optimization/15521:
	* sched-int.h (in_post_call_group_p): Change type to enum.
	* sched-deps.c (sched_analyze_insn):
	(sched_analyze): When in_post_call_group_p is post_call_initial,
	don't add a dependency, but still set SCHED_GROUP_P and CANT_MOVE,
	and also reset in_post_call_group_p to post_call.
	(sched_analyze): When the previous basic block ended in a CALL_INSN,
	initialize in_post_call_group_p as post_call_initial.
	(init_deps): initialize in_post_call_group_p to not_post_call.
