Craig Topper 3a62ce44b4 [APInt] Add setLowBits/setHighBits methods to APInt. ...

Summary:
There are quite a few places in the code base that do something like the following to set the high or low bits in an APInt.

KnownZero |= APInt::getHighBitsSet(BitWidth, BitWidth - 1);

For BitWidths larger than 64 this creates a short lived APInt with malloced storage. I think it might even call malloc twice. Its better to just provide methods that can set the necessary bits without the temporary APInt.

I'll update usages that benefit in a separate patch.
