BLORP doesn't program 3DSTATE_VF, since it doesn't use index buffers,
making the setting irrelevant. So there's no need to re-emit it after
a BLORP operation - the old setting will still be in place.

The whole "it might be used for non-indexed draws" thing is no longer
true - it turns out this was a mistake, and removed in OpenGL 4.5.
(See Marek's commit 96cbc1ca29e0b1f4f4d6c868b8449999aecb9080.) So
we can simplify this and just program 0 for non-indexed draws.
We can also use #if blocks to remove the atom on Ivybridge/Baytrail,
now that they have a separate atom list from Haswell. No more runtime
checks.

Yes, this is a bit hacky but we don't really have the choice.
Plain GLSL doesn't accept bindless samplers/images as l-values
while it's allowed when ARB_bindless_texture is enabled.
The default NULL parameter is because we can't access the
_mesa_glsl_parse_state object in few places in the compiler.
One is_lvalue(NULL) call is for IR validation but other checks
happen elsewhere, should be safe.

In plain GLSL, sampler and image types can only be declared
uniform-qualified global variables or 'in' function parameters.
Setting the read_only flag seems quite useless because other
checks will prevent sampler/image variables to be assigned and
also because the flag is not set for atomic_uint types which are
opaque types.
This will also help for ARB_bindless_texture because samplers
and images can be assigned when they are considered bindless.

Bindless samplers/images are 64-bit unsigned integers, which
means they consume two components as specified by
ARB_bindless_texture.
It looks like we are not wasting uniform storage by changing
this because default-block uniforms are not packed. So, if
we use N uint uniforms, they occupy N * 16 bytes in the
constant buffer. This is something that could be improved.
Though, count_uniform_size needs to be adjusted to not count
a sampler (or image) twice.
As a side effect, this will probably break the cache if you
have one because it will consider sampler/image types as
two components.

The ARB_bindless_texture spec says:

and,
"Images are represented using 64-bit integer handles."
It seems simpler to always consider sampler and image types
as 64-bit unsigned integer.
This introduces a temporary workaround in _mesa_get_uniform()
because at this point no flag are used to distinguish between
bound and bindless samplers. This is going to be removed in a
separate series. This avoids breaking arb_shader_image_load_store-state.
