At some point in the past we made brw_type_for_nir_type() only accept
bit-sized alu types, so this patch was necessary for things to work.
That's not the case now so this patch should not be necessary anymore
(a quick run of the fp64 tests shows no regressions without this
patch). I guess it does not hurt to add the bit-size information when
it is known though, but I think it is safe to drop this if you think it
is not worth it.
