intel/fs: Shuffle can't handle source modifiers
On Gen7, we have to split shuffles into two MOVs for 64-bit types so we
can't handle source modifiers. On Gen12.5, we have to use integer types
all the time so we can't use them there either. Fixing that will be a
different commit but it interacts with this one.
