Tim Northover c43df20a4d CodeGen: extend RHS when splitting ATOMIC_CMP_SWAP_WITH_SUCCESS. ...

If the operation's type has been promoted during type legalization, we
need to account for the fact that the high bits of the comparison
operand are likely unspecified.

The LHS is usually zero-extended, but MIPS sign extends it, so we have
to be slightly careful.

Patch by Simon Dardis.
