In OpenGL, most queries record statistics about operations performed
between a defined beginning and ending point. However, TIMESTAMP
queries are different: they immediately return a single value, and there
is no start/stop mechanism.
Previously, Mesa implemented TIMESTAMP queries by calling EndQuery
without first calling BeginQuery. Apparently this is DirectX
convention, and Gallium followed suit. I personally find the asymmetry
jarring, however---having BeginQuery and EndQuery handle a different set
of enum values looks like a bug. It's also a bit confusing to mix the
one-shot query with the start/stop model.
So, add a new QueryCounter driver hook for implementing TIMESTAMP. For
now, fall back to EndQuery to support drivers that don't do the new
mechanism.

On Gen6, lower this to `ld` with lod=0 and an extra sample_index
parameter.
On Gen7, use `ld2dms`. We don't support CMS yet for multisample
textures, so we just hardcode MCS=0. This is ignored for IMS and UMS
surfaces.
Note: If we do end up emitting specialized shaders based on the MSAA
layout, we can emit a slightly shorter message here in the UMS case.
Note: According to the PRM, `ld2dms` takes one more parameter, lod.
However, it's always zero, and including it would make the message too
long for SIMD16, so we just omit it.
V2: Reworked completely, added support for Gen7.
V3: - Introduce sample_index parameter rather than reusing lod
- Removed spurious whitespace change
- Clarify commit message
V4: - Fix comment style
- Emit SHADER_OPCODE_TXF_MS on Gen6. This was benignly wrong since
it lowers to `ld` anyway on this gen, but still wrong.

On Gen7, use `ld2dms`. This takes an additional MCS parameter to support
compressed multisample surfaces, but we're not enabling them for

omitted.

This is very similar to the TXF opcode, but lowers to `ld2dms` rather
than `ld` on Gen7.
V4: - add SHADER_OPCODE_TXF_MS to is_tex() functions, so regalloc thinks
it actually writes the correct number of registers. Otherwise in

Gen7 has an erratum affecting the ld_mcs message, making it unsafe to
use when the surface doesn't have an associated MCS.
From the Ivy Bridge PRM, Vol4 Part1 p77 ("MCS Enable"):
"If this field is disabled and the sampling engine <ld_mcs>
message is issued on this surface, the MCS surface may be
accessed. Software must ensure that the surface is defined
to avoid GTT errors."
To allow the shader to treat all surfaces uniformly, force UMS if the
surface is to be used as a multisample texture, even if CMS would have
been possible.
V3: - Quoted erratum text

The surface_state setup for renderbuffers already worked; only the

own surface_state setup.

Adds the new texture targets, and per-image state for GL_TEXTURE_SAMPLES
and GL_TEXTURE_FIXED_SAMPLE_LOCATIONS.
V2: - Allow multisample texture targets in glInvalidateTexSubImage too.
This was already partly there, but I missed it the first time around
since the interaction is defined in a newer extension. Fixed weird
indentation.
- Allow multisample array textures in glFramebufferTextureLayer.
This was overlooked as the tests originally only used 2d
multisample textures.
V3: - Set min/mag filters sensibly for multisample textures. This
can't actually be changed by the user, so it's more sensible to
initialize it correctly than to hack around it being bogus later.
V4: - Tidy up initial min/mag filter setup. Setup in
_mesa_initialize_texture_object was bogus, but benign since
finish_texture_init() clobbered everything with correct values. For V4,
just do the setup in finish_texture_init().

The GLX extension lets you expose visuals that explicitly guarantee you
that the GL_FRAMEBUFFER_SRGB_CAPABLE flag will be set, but we can set
the flag even while the visual doesn't provide the guarantee. This
appears to be consistent with other implementations, as we've seen
several apps now that don't require an srgb visual and assume sRGB will
work without checking the GL_FRAMEBUFFER_SRGB_CAPABLE flag.

Many GPUs have an instruction to do linear interpolation which is more
efficient than simply performing the algebra necessary (two multiplies,
an add, and a subtract).
Pattern matching or peepholing this is more desirable, but can be
tricky. By using an opcode, we can at least make shaders which use the
mix() built-in get the more efficient behavior.
Currently, all consumers lower ir_triop_lrp. Subsequent patches will
actually generate different code.
v2 [mattst88]:
- Add LRP_TO_ARITH flag to ir_to_mesa.cpp. Will be removed in a
subsequent patch and ir_triop_lrp translated directly.

When you didn't have a texcoord array bound (or a non-1 current w
attrib), we were telling the fragment shader that it could just use "1"
instead of doing expensive pre-gen6 math to invert it. If you drew the
point with a non-1 W value, then you'd get the right size (since all the
vertex computations worked), but we'd mis-interpolate the coordinate
across the face.
