	PR tree-optimization/91929
	* tree-ssa-pre.c (pre_expr_d::loc): New member.
	(get_or_alloc_expr_for_name): Initialize it.
	(get_or_alloc_expr_for_constant): Likewise.
	(phi_translate_1): Copy it.
	(create_expression_by_pieces): Use the original location
	of the expression for the inserted stmt.
	(compute_avail): Record the location of the stmt for the
	expressions created.
