[PowerPC][NFC] Testing ROTL of v1i128.
Summary: A bug is reported in bugzilla-45628, where the swap_with_shift case can’t be matched to a single HW instruction xxswapd as expected. In fact the case matches the idiom of rotate, but PPC doesn’t support ROTL v1i128. This is a NFC patch for testing ROTL with v1i128 at master.
