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

I haven't tried to measure any compile time differences. I was just inspired by Simon's patch for setBits and observing that ORing getLowBits/getHighBits was a common idiom in some places like ValueTracking. I assume we aren't often dealing larger than 64-bit numbers there on most types of compiled code.
