012aa622 - SIL: when updating borrowed-from instructions, remove the old enclosing values first

SIL: when updating borrowed-from instructions, remove the old enclosing values first When an optimization updates borrowed-from instruction it might be necessary to remove the old enclosing values from the borrowed-from instructions. An optimization might transform the SIL in a way that an existing enclosing value is not valid anymore. Fixes a compiler crash: rdar://142991910
