This stuff is really for software rendering, it's not core Mesa.
A small step toward pushing the FetchTexel() stuff down into swrast.

x86_64_entry_start needs to be declared static in the C code,
in order to have the correct address in entry_get_public
(seems not to be needed on x86).
The compiler needs to lookup a local not a global object.
Otherwise addresses needed for _glapi_proc_address will be computed
from some random offset (0x6400229a61058b48 in my case).
This sadly requires work in the VS to rescale them, because the
hardware doesn't support this format natively.
Fixes arb_es2_compatibility-fixed-type and gtf/fixed_data_type.

The function was named "find_unconditional_discard", but didn't
actually check that the discard statement found was unconditional.
Fixes piglit glsl-fs-discard-04.

A trivial fix for error: format not a string literal and no format
arguments with compiling with -Werror=format-security flags.

If either depth or stencil buffer has packed depth/stencil format, then do
not use separate stencil.
Before this commit, emit_depthbuffer() incorrectly assumed that the
texture's stencil renderbuffer wrapper was a *separate* stencil buffer,
because the depth and stencil renderbuffer wrappers are distinct for
depth/stencil textures (that is, depth_irb != stencil_irb).

CONFIG regs (byte offsets 0x8000-0xac00) are single state and the pipeline
must be flushed and hw idle when they are changed. Border color regs
are in the CONFIG range and this is why a flush is required when changing
them. CONTEXT regs (byte offset 0x28000+) are multi-state and those do
not require flushes when changing them.

This is just like PointSprite overrides, but it's always on for that
attribute.
Fixes glsl-fs-pointcoord, gtf/point_sprites.

We were assuming that the input attribute n to the FS was
FRAG_ATTRIB_TEXn, which happened to be true often enough for our
testcases.

If the wrap R (3rd) mode is set to CLAMP or CLAMP_TO_BORDER and the texture
isn't 3D, r300 always samples the border color regardless of texture
coordinates.
I HATE THIS HARDWARE.
NOTE: This is a candidate for the 7.10 branch.
Ideally we'd have a compiler and register spilling and all that
but this is good enough for now to avoid the gpu hang in piglit,
glsl-vs-vec4-indexing-temp-dst-in-nested-loop-combined
on r600/r700 cards.
