tree-cfg.c (gimple_split_block): Remove loop finding stmt to split on. 

2015-03-12  Richard Biener  <rguenther@suse.de>

	* tree-cfg.c (gimple_split_block): Remove loop finding stmt
	to split on.
	* omp-low.c (expand_omp_taskreg): Split block before removing
	the stmt.
	(expand_omp_target): Likewise.
	* ubsan.c (ubsan_expand_null_ifn): Adjust stmt if we replaced it.
	* tree-parloops.c (create_call_for_reduction_1): Pass a proper
	stmt to split_block.
