[InstCombine] Add one-use limitation to box multiply fold (#72876)
Check the operands of I are used in no more than one place, which can
not be deleted, cause a mul instruction has far more weight than add and
shl instruction in IR, thus this method cannot achieve the goal of
simplifying instructions, just return null.
