Kenneth Graunke c45e235df5 intel/brw: Drop NF type support 
Icelake removed the PLN instruction for interpolating fragment shader
inputs, instead adding a special "Native Float" (NF) data type which
was a 66-bit floating point data type that could only be used with the
accumulator.  On Tigerlake, they dropped NF support in favor of just
doing the interpolation with MAD instructions.

We stopped using NF years ago (commit 9ea90aae1e),
instead just using the fs_visitor::lower_linterp() pass to emit MADs.

Since this existed only for a short time, and had very limited utility,
we drop it from the compiler.  One downside is that we can no longer
disassemble Icelake shaders containing NF types properly, but I doubt
anyone really minds.
