This required building a shader parser that would walk the program to find
where the texturing-related uniforms are in the uniforms stream.
Note that as of this commit, a new kernel is required for rendering on
actual VC4 hardware (currently that commit is named "drm/vc4: Introduce
shader validation and better command stream validation.", but is likely to
be squashed as part of an eventual merge of the kernel driver).
This ensures that when I'm using the simulator, I get a closer match to
what behavior on real hardware will be. It lets me rapidly iterate on the
kernel validation code (which otherwise has a several-minute turnaround
time), and helps catch buffer overflow bugs in the userspace driver
faster.
Only rgba8888 works, and only a single texture unit, and it's only under
simulation because I haven't built the kernel interface yet.

This limit is fixed in Mesa core and cannot be changed.
It only affects ARB_vertex_program and ARB_fragment_program.
The minimum value for ARB_vertex_program is 1 according to the spec.
The maximum value for ARB_vertex_program is limited to 1 by Mesa core.
The value should be zero for ARB_fragment_program, because it doesn't
support ARL.
Finally, drivers shouldn't mess with these values arbitrarily.

Setting Const.MaxSamples needed a rework, so that it doesn't call
st_choose_format, which depends on st_context.
Other than that, there is no change in functionality.

The formats are emulated by translating them into plain uncompressed

This is required for GLES 3.0 and ARB_ES3_compatibility (GL 4.3).
This casues problems when converting atomics to use the GRF. Sometimes the atomic operation would get eaten by CSE when it shouldn't.

This provides an implementation of CopyImageSubData that works if both
textures are uncompressed. This implementation works by using a
combination of texture views and BlitFramebuffer. If one of the textures
is compressed, it returns false and the driver is expected to provide a
fallback.
