i965: Allow indirect GS input indexing in the scalar backend.
This allows arbitrary non-constant indices on GS input arrays,
both for the vertex index, and any array offsets beyond that.
All indirects are handled via the pull model. We could potentially
handle indirect addressing of pushed data as well, but it would add
additional code complexity, and we usually have to pull inputs anyway
due to the sheer volume of input data. Plus, marking pushed inputs
as live due to indirect addressing could exacerbate register pressure
problems pretty badly. We'd need to be careful.

i965/nir: Validate that NIR passes call nir_metadata_preserve().
Failing to call nir_metadata_preserve() can have nasty consequences:
some pass breaks dominance information, but leaves it marked as valid,
causing some subsequent pass to go haywire and probably crash.
This pass adds a simple validation mechanism to ensure passes handle
this properly. We add a new bogus metadata flag that isn't used for
anything in particular, set it before each pass, and ensure it *isn't*
still set after the pass. nir_metadata_preserve will reset the flag,
so correct passes will work, and bad passes will assert fail.

i965: Prevent fast clears for MSRTs on SKL
There are currently a bunch of formats that behave strangely when
sampling the cleared color from the MCS buffer on SKL. They seem to
mostly be formats that don't have an alpha component, although it's
not all of them, and we haven't yet found anything in the specs which
would explain this. For now to be on the safe side this patch just
prevents fast clears for MSRTs on SKL altogether so that when fast
clears are eventually enabled it will only be for single-sampled
surfaces. The assumption is that clears are probably more likely to be
used in single-sampled applications anyway so we can at least get them
working and we can enable MSRTs later once we understand the problem
better.
This patch should have no functional effect other than perhaps
receiving fewer perf_debug messages on SKL+.

clears because it will be merged before fast clears are enabled
for any surfaces so it doesn't actually disable anything.

meta/generate_mipmap: Only modify the draw framebuffer binding in fallback_required
Previously GL_FRAMEBUFFER was used. However, if GL_EXT_framebuffer_blit
is supported (note: it is supported by every Mesa driver), this is
*sometimes* an alias for GL_DRAW_FRAMEBUFFER (getters) and *sometimes*
an alias for *both* GL_DRAW_FRAMEBUFFER and GL_READ_FRAMEBUFFER
(setters). As a result, the code saved one binding but modified both.
If the bindings were different, the GL_READ_FRAMEBUFFER would be
incorrect on exit.
Fixes the piglit fbo-generatemipmap-versus-READ_FRAMEBUFFER test.
Ideally this function would use DSA functions and not modify the binding
at all. However, that would be a much more intrusive change because
_mesa_meta_bind_fbo_image would also need to be modified.
_mesa_meta_bind_fbo_image has a lot of callers. Much of this code is
about to get a major rework due to bug #92363, so I don't think it
matters too much. In fact, I discovered this bug while working on the

i965: Introduce a MOV_INDIRECT opcode.
The geometry and tessellation control shader stages both read from
multiple URB entries (one per vertex). The thread payload contains
several URB handles which reference these separate memory segments.
In GLSL, these inputs are represented as per-vertex arrays; the
outermost array index selects which vertex's inputs to read. This
array index does not necessarily need to be constant.
To handle that, we need to use indirect addressing on GRFs to select
which of the thread payload registers has the appropriate URB handle.
(This is before we can even think about applying the pull model!)
This patch introduces a new opcode which performs a MOV from a
source using VxH indirect addressing (which allows each of the 8
SIMD channels to select distinct data.)
Based on a patch by Jason Ekstrand.

working on Tesla. His original work can be found here:
https://github.com/curro/mesa/commits/nv50-compute
I did some improvements on the original code, like fixing using both 3D
and COMPUTE simultaneously, improving global buffers binding, and making
the code closer to what nvc0 already does. This compute support has been
tested by Pierre Moreau and myself with some compute kernels. This is a
step towards OpenCL.
Speaking about this, it seems like compute programs overlap fragment
programs when they are used both. To fix this, we need to re-validate
fragment programs when binding compute programs and vice versa.
