Kang Zhang 19f5254989 [PowerPC] Set v1i128 to expand for SETCC to avoid crash
Summary:
PPC only supports the instruction selection for v16i8, v8i16, v4i32,
v2i64, v4f32 and v2f64 for ISD::SETCC, don't support the v1i128, so
v1i128 for ISD::SETCC will crash.

This patch is to set v1i128 to expand to avoid crash.
