This fixes a regression (failed assertion) from commit
c552f273f5 which was hit if glDeleteBuffers()
was called on a buffer that was never bound.
NOTE: this is a candidate for the 7.9 branch.
Currently r600_resource_copy_region() will turn these copies into
transfers + memcpys, so to avoid recursion we must not turn those
transfers back into blits.
Previously queries of MAX_SAMPLES were only allowed with
ARB_framebuffer_object, but EXT_framebuffer_multisample also enables
this query. This seems to only effect the i915. All other drivers
support both extensions or neither extension.
This patch is based on a patch that Kenneth sent along with the report.
NOTE: this is a candidate for the 7.9 branch.

For driver performance analysis it usefull to be able to
disable as much as possible the GPU interaction so that
one can profile the userspace only.

IF statements were getting flattened while they were broken. With
Zhenyu's last fix for ENDIF's type, everything appears to have lined
up to actually work.
This regresses two tests:
glsl1-! (not) operator (1, fail)
glsl1-! (not) operator (1, pass)
but fixes tests that couldn't work before because the IFs couldn't be
flattened:
glsl-fs-discard-01
occlusion-query-discard
(and, naturally, this should be a performance improvement for apps
that actually use IF statements to avoid executing a bunch of code).
Sometimes we swizzled in a different channel it looked like, and
sometimes we swizzled in zero. Or something.
Having looked at the output of another code generator for this chip,
this is approximately what they do, too: use align1 math on
temporaries, and then move the results into place.
Fixes:
glean/vp1-EX2 test
glean/vp1-EXP test
glean/vp1-LG2 test
glean/vp1-RCP test (reciprocal)
glean/vp1-RSQ test 1 (reciprocal square root)
shaders/glsl-cos
shaders/glsl-sin
shaders/glsl-vs-masked-cos
shaders/vpfp-generic/vp-exp-alias
Instead of messing with the callers simply copy our inputs into a
alloca array at the beginning of the function and then use it.

DD_POINT_SIZE was broken for quite some time, and the only driver (r200) relying
on this no longer needs it.
Both DD_POINT_SIZE and DD_LINE_WIDTH have no users left outside of debugging
output, hence instead of fixing DD_POINT_SIZE setting just drop both of them -
there was a plan to remove tricaps flags entirely at some point.
DD_POINT_SIZE got never set for some time now (as it was set only in ifdefed
out code), which caused the r200 driver to use the point primitive mistakenly
in some cases which can only do size 1 instead of point sprite. Since the
logic to use point instead of point sprite prim is flaky at best anyway (can't
work correctly for per-vertex point size), just drop this and always emit point
sprites (except for AA points) - reasons why the driver tried to use points for
size 1.0 are unknown though it is possible they are faster or more conformant.
Note that we can't emit point sprites without point sprite cntl as that might
result in undefined point sizes, hence need drm version check (which was
unnecessary before as it should always have selected points). An
alternative would be to rely on the RE point size clamp controls which could
clamp the size to 1.0 min/max even if the SE point size is undefined, but currently
always use 0 for min clamp. (As a side note, this also means the driver does
not honor the gl spec which mandates points, but not point sprites, with zero size
to be rendered as size 1.)
This should fix recent reports of https://bugs.freedesktop.org/show_bug.cgi?id=702.
This is a candidate for the mesa 7.9 branch.
Fixes assertion failure with texture swizzling in the GLSL path when
it's triggered (such as gen6 FF or ARB_fp shadow comparisons).
Fixes:
texdepth
texSwizzle

fp1-LIT test 3
Also fixup code comment to reflect that the GPU requires DWORD
alignment, but in this case does not actually pass the value "in
DWORDs" as I previously stated.
This reverts commit 76360d6abc. On
second thought, it turned out that sync objects also used the
wait_rendering API like this, and would need the same treatment, and
so wait_rendering itself is fixed in libdrm now.
We were asking for a wait to GTT read (all GPU rendering to it
complete), instead of asking for all GPU reading from it to be
complete. Prevents swapbuffers-based apps from running away with
rendering, and produces a better input experience.
For some reason I though we needed the _DISCARD flag to avoid
readbacks, which isn't true at all. Now write operations should
pipeline properly, gives a good speedup to demos/tunnel.
