LGTM

I think we left the RISC domain :-)

The name VtblX is somewhat confusing, because there is a variant of the vtbl
instruction called vtblx, but this test has nothing to do with it.
It becomes clear when you see the name of the following tests. Feel free to
ignore.

I don't think we'll need the vtblx instruction, so I'll leave this as-is.
