[PowerPC] Zero-extend the compare operand for ATOMIC_CMP_SWAP Part of the fix for https://bugs.llvm.org/show_bug.cgi?id=35812. This patch ensures that the compare operand for the atomic compare and swap is properly zero-extended to 32 bits if applicable. A follow-up commit will fix the extension for the SETCC node generated when expanding an ATOMIC_CMP_SWAP_WITH_SUCCESS. That will complete the bug fix.
