re PR regression/58165 (internal compiler error: verify_flow_info) 

PR tree-optimization/58165
	* tree-call-cdce.c (shrink_wrap_one_built_in_call): If
	bi_call must be the last stmt in a bb, don't split_block, instead
	use fallthru edge from it and give up if there is none.
	Release conds vector when returning early.

	* g++.dg/opt/pr58165.C: New test.
