re PR rtl-optimization/22053 (ACATS ICE cxg2002 cxg2008 cxg2019 cxg2020 cxg2021 compensate_edge, at reg-stack.c:2671)


	PR rtl-optimization/22053
	* reg-stack.c (compensate_edge): Correct mistake in the assertion
	checking of EDGE_ABNORMAL_CALL edges; complex return values can
	result in the top two stack slots, st(0) and st(1), being live.
