write ("before") and the corresponding sample read ("after"), but we were
handing in the two instructions swapped.

This meant that we tried to fit things between a tex_s and its *preceding*
tex_result.  This made us only interleave normal texture coordinates by
accident, and pessimized UBO reads by pushing the tex_result collection
earlier until there was nothing but it (and then its preceding coordinate

anv: Don't include two different pack headers

The batch chain logic only needs the pre-gen8 size of
MI_BATCH_BUFFER_START, which seems like something we can make a special
case for. The other two gen7 references, MI_BATCH_BUFFER_END and
MI_NOOP, are the same on all gens.

glsl: use linked_shaders bitmask to iterate stages for subroutine fields

This should be faster than looping over every stage and null checking, but
will also make the code a bit cleaner when we switch to getting more fields
from gl_program rather than from gl_linked_shader as we can just copy the
pointer and not need to worry about null checking then copying.

This change is also required to be able to use gl_program

mesa/glsl: add bitmask to track stages a program was linked against

This will be used to enable us to store the current gl_program
rather than gl_shader_program in the gl_pipline_object allowing
us to simplify handing of validation.

Also we should not be depending on _LinkedShader for this information
as it may contain shaders from a failed linking attempt rather than
the current program still in use.

We could also use this mask to iterate over the stages during linking
with _mesa_bit_scan() rather then the current method of NULL checking
each stage.
