It seems something went wrong during conversion of this article (or
maybe even before in the HTML version), where every header after the
"Gallium environment variables" header was nested below it.
That's clearly not what's meant here, so let's fix that.
This makes the toctree make a bit more sense for this article.

Not doing this for APUs because spilling is quite likely, due to
overall VRAM pressure.
Also adding a flag to disable for performance debugging.
Finally adds some memset for places where we depended on the memory
being initialized to zero, which we won't get with VRAM anymore.
(I think these places should stop depending on it since it hides
issues with executing the cmdbuffer multiple times, but this
preserves behavior)

This causes our TGSI to use far more temps, since NTT is currently not
releasing temps from registers. On the other hand, this interpreter is
already spectacularly slow, and if we wanted to go fast we should probably
write a scalar NIR intrepeter.
For now, using NTT means that we test that codepath in preparation for
switching TGSI-consuming HW drivers over, so that we can eventually
garbage collect st_glsl_to_tgsi.
As this is a major restructuring, there are some impacts on piglit:
- Several tests start assert failing about 64-bit NIR registers for temp
arrays not getting split to vec2s:
- fs-frexp-dvec4-variable-index.shader_test
- arb_gpu_shader_fp64/uniform_buffers/{vs,fs,gs}-array-copy.shader_test
- arb_gpu_shader_int64/execution/indirect-array-two-accesses.shader_test
- dEQP-GLES31.functional.primitive_bounding_box.wide_points.global_state.vertex_geometry_fragment.fbo_bbox_larger
starts crashing depending on various bits of state (previous tests run
before it, presence of valgrind, presence of glib's memcheck). Doesn't
seem really NTT-specific, added to flakes list with other GS flakes.
- Almost 200 fp64/int64-related tests start passing, mostly around i/o loayout.

On some systems it is problematic to have the shader cache enabled
by default. This adds a build option to support the disk cache but
keep it disabled unless the environment variable
MESA_GLSL_CACHE_DISABLE=false.
For example, on Chrome OS, Chrome already has it's own shader
disk cache implementation so it disables the mesa feature. Tests
do not want the shader disk cache enabled because it can cause
inconsistent performance results and the default 1GB for the
disk cache could lead to problems that require more effort to
work around. The Mesa shader disk cache is useful for VMs though,
where it is easy to configure the feature with environment
variables. With the current version of Mesa, Chrome OS would need
to have a system-wide environment variable to disable the disk
cache everywhere except where needed. More elegant to just build
Mesa with the cache feature disabled by default.
