[X86] Add custom type legalization for SIGN_EXTEND_VECTOR_INREG from 16i16/v32i8 to v4i64 when v4i64 needs splitting.
This allows us to sign extend to v4i32 first. And then share that extension to implement the final steps to v4i64 using a pcmpgt and punpckl and punpckh.
We already do something similar for SIGN_EXTEND with -x86-experimental-vector-widening-legalization.
