x AND <constant> will result in a zero-extended representation for a
variety of constants, not just 1. For example
For example x AND 3, x AND 7, x AND 15, etc.
If (const_int 1) is really that special here, then I've either
completely misunderstood the intention of your patch or there's
something quite special about the PPC port that I'm not aware of.
