The CS thread is needed to ensure proper ordering of operations and can't
be disabled (without complicating the code).

Fixes a number of transform feedback tests when run with Linux 4.8,
which allows us to use the MI_LOAD_REGISTER_REG command, at which point
we started using this new broken path.
ES3-CTS.functional.transform_feedback.array_element.interleaved.lines.*
and Piglit's arb_transform_feedback2/draw-auto are both fixed by this
patch, for example.
Thanks to Chris Wilson for catching this mistake!

A while ago, we stopped using Luca's GLSL IR lower_jumps pass in favor
of nir_lower_returns(). Marek's commit d3cb79e043
put it in do_common_optimization, which resulted in us calling it again.
Dropping the EmitNoMainReturn setting makes us skip that pass again.
Apparently that pass doesn't work properly, because this fixes Piglit's
tests/spec/glsl-1.10/execution/vs-nested-return-sibling-loop.

The T images are composed of effectively swizzled-around blocks of LT (4x4
utile) images, so we can reduce the t_utile_address() calls by 16x by
calling into the simpler LT loop.
This also adds support for calling down with non-utile-aligned
coordinates, which will be part of lifting the utile alignment requirement
on our callers and avoiding the RMW on non-utile-aligned stores.

Improves 1024x1024 GetTexImage by 2.242% +/- 0.880954% (n=32)
They now have less of a dependency on the cpp, and don't have to do a
divide.
Hacking up mesa-demos teximage to do only one subtest and not draw
points, I saw 1024x1024 glTexSubImage2D() improve by 4.86939% +/-
1.40408% (n=30) and glGetTexImage() by 2.18978% +/- 0.140268% (n=5).
If we get up toward 256MB (or whatever the CMA area size is),
VC4_GEM_CREATE will start throwing errors. Even if we don't trigger
that, when we flush the kernel's BO allocation for the CLs or bin
memory may end up throwing an error, at which point our job won't get
rendered at all.
Just flush early (half of maximum CMA size) so that hopefully we never
get to that point.
This will help allow us to simplify the handling of samplers by
storing them in a single location rather than duplicating them in
both gl_linked_shader and gl_program.

Making this point to a gl_program struct rather than a gl_shader_program
struct will allow use to later also make the CurrentProgram array hold
gl_program structs which in turn will allow for code simpilifcation.

Set the flag via the _mesa_init_gl_program() and NewProgram()
helpers.
In i965 we currently check for the existance of gl_shader_program
to decide if this is an ARB assembly style program or not.
Adding a flag makes the code clearer and will help removes a
dependency on gl_shader_program in the i965 codegen functions.
Also this will allow use to skip initialising sampler units for
linked shaders, we currently memset it to zero again during linking.

Having it here rather than in gl_linked_shader allows us to simplify
the code.
Also it is error prone to depend on the gl_linked_shader for programs
in current use because a failed linking attempt will free infomation
about the current program. In i965 we could be trying to recompile
a shader variant but may have lost some required fields.
