History
Nikita Popov f7d1baa414 [KnownBits] Return zero instead of unknown for always poison shifts 
For always poison shifts, any KnownBits return value is valid.
Currently we return unknown, but returning zero is generally more
profitable. We had some code in ValueTracking that tried to do this,
but was actually dead code.
