emitting an unnecessary MOV instruction.

glsl: Treat ir_dereference_array of non-var as a constant for lowering
Previously the code would just look at deref->array->type to see if it
was a constant. This isn't good enough because deref->array might be
another ir_dereference_array... of a constant. As a result,
deref->array->type wouldn't be a constant, but
deref->variable_referenced() would return NULL. The unchecked NULL
pointer would shortly lead to a segfault.
Instead just look at the return of deref->variable_referenced(). If
it's NULL, assume that either a constant or some other form of
anonymous temporary storage is being dereferenced.
This is a bit hinkey because most drivers treat constant arrays as
uniforms, but the lowering pass treats them as temporaries. This
keeps the behavior of the old code, so this change isn't making things
worse.

Due to the way it tracked whether the array was being assigned, it

i965: Enable the PIPE_CONTROL workaround workaround out of paranoia.

i965: Avoid kernel BUG_ON if we happen to wait on the pipe_control w/a BO.
For this and occlusion queries, we're trying to avoid setting
I915_GEM_DOMAIN_RENDER for the write domain, because the data written
is definitely not going through the render cache, but we do need to
tell the kernel that the object has been written. However, with using
I915_GEM_DOMAIN_GTT, the kernel on retiring the batchbuffer sees that
the w/a BO has a write domain of GTT, and puts it on the flushing
list. If something tries to wait for that BO to finish rendering
(such as the AUB dumper reading the contents of BOs), we get into
wait_request (since obj->active) but with a 0 seqno (since the object
is on the flushing list, not actually on a ringbuffer), and BUG_ONs.
To avoid the kernel bug (which I'm hoping to delete soon anyway), just
use I915_GEM_DOMAIN_INSTRUCTION like occlusion queries do. This
doesn't result in more flushing, because we invalidate INSTRUCTION on
every batchbuffer now that we're state streaming, anyway.

glsl: Avoid massive ralloc_strndup overhead in S-Expression parsing.
When parsing S-Expressions, we need to store nul-terminated strings for
Symbol nodes. Prior to this patch, we called ralloc_strndup each time
we constructed a new s_symbol. It turns out that this is obscenely
expensive.
Instead, copy the whole buffer before parsing and overwrite it to
contain \0 bytes at the appropriate locations. Since atoms are
separated by whitespace, (), or ;, we can safely overwrite the character
after a Symbol. While much of the buffer may be unused, copying the
whole buffer is simple and guaranteed to provide enough space.
Prior to this, running piglit-run.py -t glsl tests/quick.tests with GLSL
1.30 enabled took just over 10 minutes on my machine. Now it takes 5.
NOTE: This is a candidate for stable release branches (because it will
make running comparison tests so much less irritating.)

intel: Fix stencil buffer to be W tiled
Until now, the stencil buffer was allocated as a Y tiled buffer, because
in several locations the PRM states that it is. However, it is actually
W tiled. From the PRM, 2011 Sandy Bridge, Volume 1, Part 2, Section
4.5.2.1 W-Major Format:
W-Major Tile Format is used for separate stencil.
The GTT is incapable of W fencing, so we allocate the stencil buffer with
I915_TILING_NONE and decode the tile's layout in software.
This fix touches the following portions of code:
- In intel_allocate_renderbuffer_storage(), allocate the stencil
buffer with I915_TILING_NONE.
- In intel_verify_dri2_has_hiz(), verify that the stencil buffer is
not tiled.
- In the stencil buffer's span functions, the tile's layout must be
decoded in software.
