Henrik GramnerandLuca Barbato a344e5d094 x86: bswapdsp: Don't treat 32-bit integers as 64-bit 
The upper halves are not guaranteed to be zero in x86-64.

Also use `test` instead of `and` when the result isn't used for anything other
than as a branch condition, this allows some register moves to be eliminated.
