If we don't update this for all primitive-types, we end up rendering
slightly offset points and lines up until the point where the first
triangle gets drawn. This is obviously not correct, and violates
OpenGL's repeatability rule.

Use a different arrangement of constants to allow more ffma.
A vec4 backend will now use 3 fma for yuv_to_rgb. On freedreno/ir3, it is
down from 10 to 7 alu (4 fma, 3 mul, 3 add to 7 fma). Other backends
shouldn't be hurt.

Like with interpolatAtSample this is also not really implementing the

Since for this opcode the offsets are given manually the function
should actually also work for non-zero offsets, but the related piglits
only ever test with offset 0. Accordingly the patch satisfies

Softpipe doesn't support more than one sample, so this function
implements the interpolation at sample 0 and adds a stub to make it
possible to interpolate at other samples.
As it is this makes the piglits "fs-interpolateatsample-*" pass, but
they only ever test sample 0 anyway.

The EGL_KHR_create_context spec says:
"If an OpenGL context is requested and the values for attributes
EGL_CONTEXT_MAJOR_VERSION_KHR and EGL_CONTEXT_MINOR_VERSION_KHR,
when considered together with the value for attribute
EGL_CONTEXT_OPENGL_FORWARD_COMPATIBLE_BIT_KHR, specify an OpenGL

The shader constant buffer size with the
constant compaction code can vary depending
on the shader variant compiled (for example if
fog constants are required, etc).
Thus instead of using fixed size for the shader,
add in the variant cache the size required, pass it
to the context, and use this value.

As with the constant compaction we map the constant
slots to new slots, we need to pass that information

When indirect addressing is not used, we know exactly
which constants are accessed, and thus can
have them located in consecutive slots.
We thus parse again the shader with a slot map
for compaction.
The path contains the work inside nine_shader.c for this
path, but it needs some other commits to work, and thus
is not enabled yet by this commit.
