This fixes piglit/fbo-generatemipmap-array.
It looks like SQ_TEX_SAMPLER_WORD0_0.TEX_ARRAY_OVERRIDE should be set
for array textures in order to disable filtering between slices,
which adds a dependency between sampler views and sampler states.
This patch reworks sampler state updates such that they are postponed until
draw time. TEX_ARRAY_OVERRIDE is updated according to bound sampler views.
This also consolidates setting the texture state between vertex and
pixel shaders.
The only purpose this call served in the DRI swrast driver was to
initialize the remap table. Core Mesa already does the dispatch
offset remapping for every function that could possibly ever be
supported. There's no need to continue using that cruft in the
driver.

Since the call to _mesa_enable_imaging_extensions (via
driInitExtensions) is removed, EXT_blend_color, EXT_blend_logic_op,
and EXT_blend_minmax are no longer advertised. These all resulted in
software fallbacks, so their loss will not be mourned.
EXT_blend_subtract is, however, explicitly added to the list.
GL_FUNC_SUBTRACT is fully accelerated, but GL_FUNC_REVERSE_SUBTRACT
(still) results in a software fallback.

Trivially silence the compiler by adding '(void) foo;' for each unused
parameter. These parameters could not be removed. They are part of
interface used elsewhere in Mesa, and some of the other customers
actually use these parameters.
The internalFormat, format, and type parameters were not used by
either try_pbo_upload or try_pbo_zcopy, so remove them. The width
parameter was also not used by try_pbo_zcopy (because it doesn't
actually copy anything), so remove it too.
Eric Anholt notes:
The current structure of this code is so hateful I can't bring
myself to say anything about whether changing the current code is
good or bad.
I have a dream that one call would try to make a surface
(miptree/region) out of the PBO, then we'd see about whether it
matches up nicely and zero-copy/blit using that. That would be
reusable for texsubimage, which is currently awful in this
respect.
At some point we should revisit this code with pitchforks and torches.
The depth0 parameter was not used in intel_miptree_create_for_region,
so remove it. All of the places that call this function, pass 1 for
that parameter, and the place where it looks like it should have been
used (the call to intel_miptree_create_internal) also had 1 hard
coded.

The GLenum target parameter was not used in intel_copy_texsubimage, so
remove it. Also remove the GLenum internalFormat parameter. Each

The intel_context and tiling parameters were not used by any if the
i9[14]5_miptree_layout or the functions they call, and the tiling parameter was
not used by brw_miptree_layout. Remove the unnecessary parameters.
Also clean-up some of the naming, etc. in
intel_buffer_object_purgeable. 'intel' is usually used as the name of
an intel_context pointer, and intel_obj is usually used as the name of
an intel_*_obj pointer. These changes were suggested by Eric Anholt.

v2: Remove the assertion in intel_batchbuffer_space:

After reviewing all the places where this is called, I'm (fairly)
comfortable that this assertion was redundant. Having the assertion
adds ~20KiB to a driver build:

This differs from the FS in that we track constants in each
destination channel, and we we have to look at all the swizzled source
channels. Also, the instruction stream walk is done in an O(n) manner
instead of O(n^2).
Across shader-db, this reduces 8.0% of the instructions from 60.0% of
the vertex shaders, leaving us now behind the old backend by 11.1%
overall.
Tracking virtual GRFs has tension between using a packed array per
virtual GRF (which is good for register allocation), and sparse arrays
where there's an element per actual register (so the first and second
column of a mat2 can be distinguished inside of an optimization pass).
The FS mostly avoided the need for this second sparse array by doing
virtual GRF splitting, but that meant that instances where virtual GRF
splitting didn't work, instructions using those registers got much
less optimized.
Now instead of env INTEL_NEW_VS=1 to get it, you need INTEL_OLD_VS=1
to not get it. While it's not quite to the same codegen efficiency as
the old backend, it is not regressing piglit on G965 and G45, and
actually fixing bugs on gen6, and the remaining codegen quality
regressions all appear tractable.
