mesa: Add MESA_SHADER_CAPTURE_PATH for writing .shader_test files.

This writes linked shader programs to .shader_test files to
$MESA_SHADER_CAPTURE_PATH in the format used by shader-db
(http://cgit.freedesktop.org/mesa/shader-db).

It supports both GLSL shaders and ARB programs.  All stages that
are linked together are written in a single .shader_test file.

This eliminates the need for shader-db's split-to-files.py, as Mesa
produces the desired format directly.  It's much more reliable than
parsing stdout/stderr, as those may contain extraneous messages, or
simply be closed by the application and unavailable.

We have many similar features already, but this is a bit different:
- MESA_GLSL=dump writes to stdout, not files.
- MESA_GLSL=log writes each stage to separate files (rather than
  all linked shaders in one file), at draw time (not link time),
  with uniform data and state flag info.
- Tapani's shader replacement mechanism (MESA_SHADER_DUMP_PATH and
  MESA_SHADER_READ_PATH) also uses separate files per shader stage,
  but allows reading in files to replace an app's shader code.

v2:  Dump ARB programs too, not just GLSL.
v3:  Don't dump bogus 0.shader_test file.
v4:  Add "GL_ARB_separate_shader_objects" to the [require] block.
v5:  Print "GLSL 4.00" instead of "GLSL 4.0" in the [require] block.
v6:  Don't hardcode /tmp/mesa.
v7:  Fix memoization of getenv().
v8:  Also print "SSO ENABLED" (suggested by Timothy).
v9:  Also handle ES shaders (suggested by Ilia).
v10: Guard against MESA_SHADER_CAPTURE_PATH being too long; add
     _mesa_warning calls on error handling (suggested by Ben).
v11: Fix crash when variable is unset introduced in v10.

nvc0: re-validate images after launching a grid on Fermi

Images invalidation is a bit weird on Fermi and there is already a hack
which forces invalidating all images when launching a computer shader
to help in fixing 3D<->CP interaction.

However, we need to re-validate images for compute because
nvc0_compute_invalidate_surfaces() will destroy the previous binding.

i965/vec4: Fix cmod propagation not to propagate non-identity cmod into CMP(N).

The conditional mod of these instructions determines the semantics of
the comparison itself (rather than being evaluated based on the result
of the instruction as is usually the case for most other instructions
that allow conditional mods), so it's in general not legal to
propagate a conditional mod into a CMP instruction.  This prevents
cmod propagation from (mis)optimizing:

 cmp.z.f0 tmp, ...
 mov.z.f0 null, tmp

into:

 cmp.z.f0 tmp, ...

which gives the negation of the flag result of the original sequence.
I originally noticed this while working on SIMD32 in the scalar
back-end, but the same scenario is likely to be possible in vec4
programs so this commit ports the bugfix with the same name from the

i965: Enable cross-thread constants and compact local IDs for hsw+

The cross thread constant support appears on Haswell. It allows us to
upload a set of uniform data for all threads without duplicating it
per thread.

One complication is that cross-thread constants are loaded into
registers before per-thread constants. Previously, our local IDs were
loaded before the uniform data and treated as 'payload' data, even
though they were actually pushed into the registers like the other
uniform data.

Therefore, in this patch we simultaneously enable a newer layout where
each thread now uses a single uniform slot for a unique local ID for
the thread. This uniform is handled specially to make sure it is added
last into the uniform push constant registers. This minimizes our
usage of push constant registers, and maximizes our ability to use
cross-thread constants for registers.

To swap from the old to the new layout, we also need to flip some
lowering pass switches to let our driver handle the lowering instead.
We also no longer force thread_local_id_index to -1.

When we add support for uploading both a common (cross-thread) set of
