DXILOpLowering already has an error when it encounters a vector. Putting this
in here like this just makes it so we have to change splitdouble
implementation code to get everything working when the scalarization PR lands.
What I recomend is to create a correct Vector test case and XFAIL it.
Then when scalarization of Struct vectors lands that test will go from XFAIL
to pass and we will know we can remove XFAIL or better yet integrate those
tests with splitdouble.ll
