Sanjay Patel 6844e21f59 [InstCombineCasts] Fix checks in sext->lshr->trunc pattern. ... The comment says to avoid the case where zero bits are shifted into the truncated value, but the code checks that the shift is smaller than the truncated value instead of the number of bits added by the sign extension. Fixing this allows a shift by more than the value size to be introduced, which is undefined behavior, so the shift is capped at the value size minus one, which has the expected behavior of filling the value with the sign bit.
