Call ffs() and ffsll() everywhere. Define our own ffs(), ffsll()
functions when the platform doesn't have them.
v2: remove #ifdef _WIN32, __IBMC__, __IBMCPP_ tests inside ffs()
implementation. The #else clause was recursive.

Introduce vbo_get_minmax_indices() function to handle the min/max index
computation for nr_prims(>= 1). The old code just compute the first
prim's min/max index; this would results an error rendering if user
called functions like glMultiDrawElements(). This patch servers as
fixing this issue.
As when nr_prims = 1, we can pass 1 to paramter nr_prims, thus I made
vbo_get_minmax_index() static.
v2: per Roland's suggestion, put the indices address compuation into
vbo_get_minmax_index() instead.
Also do comination if possible to reduce map/unmap count
v3: per Brian's suggestion, use a pointer for start_prim to avoid
structure copy per loop.

Instead, do the uniform setting and input / output mapping directly in
brw_link_shader. Hurray for not generating Mesa IR! However, once
the i965 driver stops calling _mesa_ir_link_shader, UsesClipDistance
and UsesKill are no longer set.
Ideally gen6_upload_vs_push_constants should use the
gl_shader_program, but I don't see a way to propagate the information
there. The other alternative, since this is the only usage, is to
move gl_vertex_program::UsesClipDistance to brw_vertex_program.
The compile (and precompile) stages use UsesKill to determine the
cache key for the shader. This is then used to determine whether or
not to compile the shader. Calculating this data during compilation
is too late.

This previously enabled some optimizations in the fragment shader
(interpolation, etc.) if some input components were always 0.0 or
1.0. However, this data was generated by analyzing Mesa IR. The
next patch in this series removes generation of Mesa IR for GLSL
paths. When we detect that case, just set the used mask to ~0 and
circumvent the optimizations.

It used to be done in ir_to_mesa, and that was kind of a bad place.
I didn't change st_glsl_to_tgsi because there is some strange stuff
happening in the code that generates glDrawPixels shaders. It looked
like this would break horribly if I touched anything.

Rather than looking at the settings in individual assembly programs,
look at the settings in the top-level uniform values. The old code
was flawed because examining each shader stage in isolation could
allow inconsitent usage across stages (e.g., bind unit 0 to a
sampler2D in the vertex shader and sampler1DShadow in the fragment
shader).

Previously the fixed-function fragment shader was tracked as a
gl_program. This means that it shows up in the driver as a Mesa IR
program instead of as a GLSL IR program. If a driver doesn't generate
Mesa IR from the GLSL IR, that program is empty. If the program is
empty there is either no rendering or a GPU hang.

Poking directly at the backing resources works only by luck. Core
Mesa code should only know about the gl_uniform_storage structure.
Soon other code that looks at samplers will use the gl_uniform_storage
structures instead of the data in the gl_program.

It looks like AC_PROG_SED was added in 2.59b, and wasn't in the

The gen7_urb atom depends on CACHE_NEW_VS_PROG and CACHE_NEW_GS_PROG,
causing gen7_upload_urb() to be called when switching to a new VS
program.
In addition to partitioning the URB space between the VS and GS,
gen7_upload_urb() also allocated space for VS and PS push constants.
Unfortunately, this meant that whenever CACHE_NEW_VS was flagged, we'd
reallocate the space for the PS push constants. According to the BSpec,
after sending 3DSTATE_PUSH_CONSTANT_ALLOC_PS, we must reprogram
3DSTATE_CONSTANT_PS prior to the next 3DPRIMITIVE.
Since our URB allocation for push constants is entirely static, it makes
sense to split it out into its own atom that only subscribes to
BRW_NEW_CONTEXT. This avoids reallocating the space and trashing
constants.
Fixes a rendering artifact in Extreme Tuxracer, where instead of a snow
trail, you'd get a bright red streak (affectionately known as the
"bloody penguin bug").
This also explains why adding VS-related dirty bits to gen7_ps_state
made the problem disappear: it made 3DSTATE_CONSTANT_PS be emitted after
every 3DSTATE_PUSH_CONSTANT_ALLOC_PS packet.
NOTE: This is a candidate for the 7.11 branch.

However, when num_attribs == 0, it was returning true without setting

svga_sampler_view contains a pointer to a pipe_resource (base class of
svga_texture) and svga_texture contains a pointer to an svga_sampler_view.
This circular dependency prevented the objects from ever being freed when
they pointed to each other. Make the svga_sampler_view::texture pointer
a "weak reference" (no reference counting) to break the dependency.
This is safe to do because the pipe_resource/texture always has a longer
lifespan than the sampler view so when svga_sampler_view stops referencing
the texture, the texture's refcount never hits zero.
Fixes a memory leak seen with google earth and other apps.

We were naively emitting each component at a time, even if we were
emitting the same value to multiple channels. Improves on a codegen
regression from the old VS to the new VS on some unigine shaders
(because we emit constant vecs/matrices as immediates instead of
loading them as push constants, so we had over 4x the instructions for
using them).
shader-db results:
Total instructions: 58594 -> 58540
11/870 programs affected (1.3%)
765 -> 711 instructions in affected programs (7.1% reduction)
