On Gen6-7, we don't compact clip planes, and nr_userclip_plane_consts
is the last bit set, so iterating from i = 0..nr_userclip_plane_consts
covers all active clip planes and is the right thing to do.
works and is the right thing to do.
However, that doesn't work at all on Gen4-5. Since we don't compact
clip planes, we skip over ones which aren't active (via the continue
statement). We also set set nr_userclip_plane_consts to the number of
active clip planes, which means that we end the loop after checking that
many bits. If the set of clip planes wasn't contiguous, this means we'd
fail to find the last few.
By changing the iteration to MAX_CLIP_PLANES, we correctly find all of
the active clip planes.

Piglit's spec/glsl-1.20/execution/clipping/fixed-clip-enables and

Since Gen4-5 compacts clip planes and Gen6-7 doesn't, it makes sense to
split them into separate code paths. This patch simply copies the code
to both halves; the next commits will simplify it.

The previous 1023-entry chaining hash table never resized, so it was very
inefficient when there were many objects live. While one could have an even
more efficient implementation than this (keep an array for genned names with
packed IDs, or take advantage of the fact that key == hash or key ==
*(uint32_t *)data to store less data), this is fairly fast, and I want a nice
replacement hash table for other parts of Mesa, too.
It improves Minecraft performance 12.3% +/- 1.4% (n=9), dropping hash lookups
from 8% of the profile to 0.5%.
I also tested cairo-gl, which should be a pessimal workload for this hash
table: around 247000 FBOs created and destroyed, only around 65 live at any
time, and few lookups of them between creation and destruction. No
statistically significant performance difference at n=76 (mean 20.3/20.4
seconds, sd 2.8/3.2 seconds). If I remove the >20 seconds outliers that
appear to be due to thermal throttling, there's possibly a .97% +/- 0.31%
performance win (n=61/59). The choice of cutoff for outliers feels a lot like
cooking the data, but I've gone through this process 3 times for minor
iterations of the code with the same conclusion each time.

Mesa's chaining hash table for object names is slow, and this should be much
faster. I namespaced the functions under _mesa_*, to avoid visibility
troubles that we may have had before with hash_table_* functions.

Previously, we used these XML annotations to make the code generation
scripts aware of any instances where the Mesa implementation of a

This patch changes the use of const in the type signatures of
_mesa_ShaderSource() and _mesa_TransformFeedbackVaryings(), to match
the type signatures in the GL spec. This avoids warnings when
building the code-generated api_exec.c file.
Note: previously we avoided the build warnings because these functions
were being type-checked against ShaderSourceARB and
TransformFeedbackVaryingsEXT; those functions are semantically
equivalent, but have fewer const qualifiers in their type signatures.
