NIR has fdiv, and all the NIR backends have to have lower_fdiv set
appropriately already since various passes (format conversions,
tgsi_to_nir, nir_fast_normalize(), etc.) might generate one.
This causes softpipe and llvmpipe to now do actual divides, since
lower_fdiv is not set there. Note that llvmpipe's rcp implementation is a
divide of 1.0 by x, so now we're going to be just doing div(x, y) instead
of mul(x, div(1.0, y)).

Calling this directly in the linker code allows us to place it between
the varying linker and uniform linker calls which allows for better
optimisation/removal of uniforms.
Also in a later patch it allows us to insert a new nir based
lower_const_arrays_to_uniforms() call after the gl_nir_link_opts()
call. This is important because it allows the linking opts to
move constant arrays to later stages if possible before
lower_const_arrays_to_uniforms() turns them into uniforms.

For the NIR XFB gathering as well as all the Vulkan drivers, buffer

nir_xfb_info for GLSL on radeonsi, he copied directly from the GLSL
struct which has strides in dwords. This inconsistency didn't show up
until I went through and started us using the NIR passes for GL drivers
directly without going through the GLSL structs. We could change the
nir_xfb_buffer_info field to be in dwords to be consistent with
shader_info but that would mean changing all the Vulkan drivers but, for
now, it's easier to always use bytes in nir_xfb_info.

A 1D texture operation may need to do a mov to turn a reference to a

amnesia-the-dark-descent/low/46.shader_test() for example, where a 1D

Besides, the nir_op_is_vec() case will (perhaps surprisingly) look through
