intel/fs: Fix repclear assembly for XeHP+ regioning restrictions. 

The regioning mode used here is no longer supported by the
floating-point pipeline.  We could run the regioning lowering pass in
order to fix it with some extra copies, but it's more efficient to
change the instruction to use integer types.
