tree-optimization/102752: Fix determining precission of reduction_var

While determining the precission of reduction_var an SSA_NAME instead of
its TREE_TYPE is used.  Streamlined with other TREE_TYPE (reduction_var)
uses.

gcc/ChangeLog:

	* tree-loop-distribution.c (reduction_var_overflows_first):
	Pass the type of reduction_var as first argument as it is also
	done for the load type.
	(loop_distribution::transform_reduction_loop): Add missing
	TREE_TYPE while determining precission of reduction_var.
