Remarks
This option is valid only when the CPU type is H8SX or H8S(without legacy=v4 option).
When opt_range=noloop is specified, max_unroll=1 is always the default.
When opt_range=noblock is specified, max_unroll=1, const_var_propagate=0, and
global_alloc=0 are always the default.
(2) Optimization in a loop (done when opt_range=all is specified)
