SH: Fix cost estimation of mem load/store
For memory loads/stores (that contain a MEM rtx) sh_rtx_costs would wrongly
report a cost lower than 1 insn which is not accurate as it makes loads/stores
appear cheaper than simple arithmetic insns. The cost of a load/store insn is
at least 1 insn plus the cost of the address expression (some addressing modes
can be considered more expensive than others due to additional constraints).
gcc/ChangeLog:
PR target/113533
* config/sh/sh.cc (sh_rtx_costs): Adjust cost estimation of MEM rtx
to be always at least COST_N_INSNS (1). Forward speed argument to
sh_address_cost.
