  Log Message:
  -----------
  [InstCombine] Fall through to computeKnownBits() for sdiv by -1

When dividing by -1 we were breaking out of the code entirely,
while we should fall through to computeKnownBits().

This fixes an instcombine-verify-known-bits discrepancy.

Fixes https://github.com/llvm/llvm-project/issues/109957.
