  -----------
  [NFC][ValueTracking]: Remove redundant computeKnownBits call for LoadInst in isKnownNonZero

For load instructions, computeKnownBits only checks the range metadata.
This check is already present in isKnownNonZero, so there is no need to
fall through to computeKnownBits.

This change gives a speed improvement of 0.12-0.18%:
