Ulrich Weigand e9c6b63d4a [SystemZ] Simplify knownbits.ll test ...

The knownbits.ll test case is somewhat fragile since:
- it relies on undef inputs; and
- it operates just at the limits of the MaxRecursionDepth

This means that optimization changes may easily cause the test
to spuriously fail.  Rewrite the test so it still validates
the same thing, but in a less fragile manner.
