Chad Rosier c215c3fd14 [CVP] Convert an AShr to a LShr if 1st operand is known to be nonnegative. ... An arithmetic shift can be safely changed to a logical shift if the first operand is known positive. This allows ComputeKnownBits (and similar analysis) to determine the sign bit of the shifted value in some cases. In turn, this allows InstCombine to canonicalize a signed comparison (a > 0) into an equality check (a != 0).
