The matrix used for YCbCr to RGB is listed in:
https://en.wikipedia.org/wiki/YCbCr
There was an error in converting the offsets from integers to unorm
values: 0.0625=16/256 should be 16.0/255,and 0.5=128.0/256 should be
128.0/255. With this fix, the CSC result is bit aligned with wikipedia's
conversion result and FFMPeg's result.

The NIR story on conversion opcodes is a mess. We've had way too many
of them, naming is inconsistent, and which ones have explicit sizes was
sort-of random. This commit re-organizes things and makes them all
consistent:
- All non-bool conversion opcodes now have the explicit size in the
destination and are named <src_type>2<dst_type><size>.
- Integer <-> integer conversion opcodes now only come in i2i and u2u
forms (i2u and u2i have been removed) since the only difference
between the different integer conversions is whether or not they
sign-extend when up-converting.
- Boolean conversion opcodes all have the explicit size on the bool and
are named <src_type>2<dst_type>.
Making things consistent also allows nir_type_conversion_op to be moved
to nir_opcodes.c and auto-generated using mako. This will make adding
int8, int16, and float16 versions much easier when the time comes.

We rename it to nir_deref_clone, re-order the sources to match the other
clone functions, and expose nir_deref_var_clone. This past part, in
particular, lets us get rid of quite a few lines since we no longer have
to call nir_copy_deref and wrap it in deref_as_var.

This is ported from the Intel lowering pass that we use with GLSL IR.
This takes care of lowering texture gradients on shadow samplers other
than cube maps. Intel hardware requires this for gen < 8.
v2 (Ken):
- Use the helper function to retrieve ddx/ddy
- Swizzle away size components we are not interested in
v3:
- Get rid of the ddx/ddy helper and use nir_tex_instr_src_index
instead (Ken, Eric)
v4:
- Add a 'continue' statement if the lowering makes progress because it
replaces the original texture instruction

This is ported from the Intel lowering pass that we use with GLSL IR.
The NIR pass only handles cube maps, not shadow samplers, which are
also lowered for gen < 8 on Intel hardware. We will add support for
that in a later patch, at which point we should be able to remove
the GLSL IR lowering pass.
v2:
- added a helper to retrieve ddx/ddy parameters (Ken)

v4:

from the original textureGrad() (except for ddx/ddy) using a loop
- Add a 'continue' statement if the lowering makes progress because it
replaces the original texture instruction

This commit adds the capability to NIR to support separate textures and
samplers. As it currently stands, glsl_to_nir only sets the texture deref
and leaves the sampler deref alone as it did before and nir_lower_samplers
assumes this. Backends can still assume that they are combined and only
look at only at the texture index. Or, if they wish, they can assume that
they are separate because nir_lower_samplers, tgsi_to_nir, and prog_to_nir
all set both texture and sampler index whenever a sampler is required (the
two indices are the same in this case).

We're about to separate the two concepts. When we do, the sampler will
become optional. Doing a rename first makes the separation a bit more
safe because drivers that depend on GLSL or TGSI behaviour will be fine to
just use the texture index all the time.
