PR debug/44901
	* vec.h (VEC_block_remove): Fix comment.
	* tree-ssa-live.c (remove_unused_locals): Don't use
	VEC_unordered_remove on local_decls, instead replace a single
	vector element in each iteration if at least one element had
	to be removed and VEC_truncate at the end.
	* omp-low.c (expand_omp_taskreg): Likewise.
