[RISCV] Add profitability checks to SelectAddrRegRegScale. (#150135)
-Only fold if the ADD can be folded into all uses.
-Don't reassociate an ADDI if the shl+add can be a shxadd or similar
instruction.
-Only reassociate a single ADDI. If there are 2 addis it's the same
number of instructions as shl+add. If there are more than 2 that it
would increase instructions over folding the addis into the
loads/stores.
