In d1c4e64a69, we added a parameter to tell the back-end compiler to
ignore the param array and just push however many constants you ask it
to push. Iris doesn't want to push anything so it gives a bogus number
of parameters and trusts the back-end compiler to dead-code all of them.
Now that we can tell the back-end compiler to stop re-arranging things,
delete the hack and enable the new simpler code path.

In d1c4e64a69, we added a parameter to tell the back-end compiler to

but it seems to have caused a number of regressions. Revert to the old

To make PIPE_FORMATs usable from non-gallium parts of Mesa, I want to
move their helpers out of gallium. Since u_format used
util_copy_rect(), I moved that in there, too.
I've put it in a separate directory in util/ because it's a big chunk
of related code, and it's not clear to me whether we might want it as
a separate library from libmesa_util at some point.

It's kind-of an anomaly that the Intel drivers are still treating
gl_FragCoord as an input. It also makes zero sense because we have to
special-case it in the back-end.
Because ANV is the only user of nir_lower_wpos_center, we go ahead and
just update it to look for nir_intrinsic_load_frag_coord as part of this

PIPE_CAP_SM3 has always been an odd one out of all our caps. While most
other caps are fine-grained and single-purpose, this cap encode several
features in one. And since OpenGL cares more about single features, it'd
be nice to get rid of this one.
As it turns, this is now relatively simple. We only really care about
three features using this cap, and those already got their own caps. So
we can remove it, and make sure all current drivers just give the same
response to all of them.
The only place we *really* care about SM3 is in nine, and there we can
instead just re-construct the information based on the finer-grained
caps. This avoids DX9 semantics from needlessly leaking into all of the
drivers, most of who doesn't care a whole lot about DX9 specifically.

This avoids lowering of CS system values by GLSL (configured by state
tracker). In i965 we don't use that lowering, and we also shouldn't
need that in Iris.
Using it cause some unnecessary round trip between values, e.g.:
shader uses gl_LocalInvocationIndex, GLSL rewrites it in terms of
gl_LocalInvocationID, then driver rewrites those in terms of
gl_LocalInvocationIndex again. Copy propagation can make some of
those go away, but not all as seen below.

TGSI's FBFETCH instruction currently only supports reading from a single

radeonsi can only support fetching from RT 0, but other drivers may be
able to support fetching from any render target.
To express this, this patch renames PIPE_CAP_TGSI_FS_FBFETCH to simply
PIPE_CAP_FBFETCH, and converts it from a boolean "is FBFETCH supported?"
to an integer number of render targets which can be fetched.

This patch changes the GL_VENDOR string from "Mesa Project" to "Intel".
This makes GLX_MESA_query_renderer report "Vendor: Intel (0x8086)"
instead of "Vendor: Mesa Project (0x8086)" which is arguably wrong.
We now also use a consistent vendor string across Windows and Linux.
It also prepends "Mesa" to the GL_RENDERER string, both to credit the
community and have a distinguishing mark between the two drivers. We
drop "DRI" compared to i965, as it's not really that important.
Improves performance in Portal by 1.8x. Iris is now 3.86% faster

storage invalidation optimization.

Caio noted that this is not necessary on Gen8+:
"Before Gen8, there was a historical configuration control field to
swizzle address bit[6] for in X/Y tiling modes. This was set in
three different places: TILECTL[1:0], ARB_MODE[5:4], and
DISP_ARB_CTL[14:13]. For Gen8 and subsequent generations, the
swizzle fields are all reserved, and the CPU's memory controller
performs all address swizzling modifications."
Since we don't support earlier hardware, we can skip it entirely.
I had a hack in place earlier to pass the query type as q->index
for the regular statistics query, but we ended up adjusting the

batch reset, rather than batch finish time. this will work better
