Since switching to hidden visibility on gcc, GLw apps were failing to
link. Use the GLAPI definition to use default visibility where necessary.

This was spectacularly unsafe. On my system, address 0 happens to be
the hardware status page for the render ring, and the first quadword
of that happens to contain nothing we ever look at, but I sure didn't
look forward to having to debug some day when, for example, the kernel
happened to bind the ringbuffer before binding the hwsp.
That flag was leftover from gen4, where brw_curbe.c is choosing ranges
of the CURBE space for constants to live in, and the unit state tells
where to load them from. That's not the case on gen6 -- we don't set
this flag (since constants aren't in the URB), nor do we have any
state like that to upload.
Our hardware doesn't have a sample_d_c message, so we have to do a
regular sample_d and emit instructions to manually perform the
comparison.
This requires a state dependent recompile whenever the sampler's compare
mode or function change. This adds the per-sampler comparison functions
to brw_wm_prog_key, but only sets them when the sampler's compare mode
is GL_COMPARE_R_TO_TEXTURE (i.e. only for shadow sampling).

This makes it available earlier, which will soon be necessary.

This is somewhat ugly, but I couldn't think of a nicer way to handle the
interleaved coordinate/derivative parameter loading.
Ironlake and Sandybridge will still hit an assertion in visit().

Prior to this patch, it would attempt to optimize and allocate registers
for the program even if it failed to compile. This seems wasteful.
More importantly, the "message length > 11" failure seems to choke the
instruction scheduler, making it somehow use an undefined value and
segmentation fault.

There will be a little bit of thrashing of the program cache BO as the
cache warms up, but once the application is in steady state, this
reduces relocations on gen5 and later.
On my T420 laptop, cairogl firefox-talos-gfx performance improves 2.6%
+/- 1.3% (n=6). No statistically significant performance difference
on nexuiz (n=5).
The _ColorDrawBuffers[] wouldn't get updated despite us having updated
what it depends on (Attachments[]->Renderbuffer). Other callers of
_mesa_remove_attachment are already flagging _NEW_BUFFERS for other
reasons. The specific bug report that led to this fix (and
the fbo-finish-deleted testcase) was fixed by
23b6f9606d, though.

This loop is trying to see if all the buffers to be uploaded happen to
be the same increment from the start of the 3DSTATE_VERTEX_BUFFERS
currently loaded in the hardware. However, we might be at a smaller
offset than the previous set of VERTEX_BUFFERS, so we can't reuse
because that packet made the first entry be its starting offset (you
can't access outside the given bounds).
Fixes piglit ARB_vertex_buffer_object/elements-negative-offset.
Current LIT implementation uses dst components for storing temp
results, possibly overwriting still needed values (depends on the
swizzles).
This patch uses temp reg for one of such cases (found in etqw) and
fixes "LIT R.z, R.xyzz".
Tested on evergreen. Fixes some etqw-demo rendering glitches when
"Lighting" is set to "High" in the settings.
