[PATCH] D30525: [APInt] Add setLowBits/setHighBits methods to APInt.

@RKSimon , yes I think getLowBitsSet/getHighBitsSet would also benefit. I think they are mallocing twice due to the getAllOnes and then shifting. So I think we should be able to just create an all 0s APInt then call setLowBits/setHighBits instead and save one of the mallocs.
