8f4e03c397 i965/fs: Don't use brw_imm_* unnecessarily.
Using brw_imm_* creates a source with file=HW_REG, and the scheduler
inserts barrier dependencies when it sees HW_REG. None of these are
hardware-registers in the sense that they're special and scheduling
shouldn't touch them. A few of the modified cases already have HW_REGs
for other sources, so it won't allow extra flexibility in some cases.

258f35441a i965/fs: Set force_uncompressed and force_sechalf on samplepos setup.
gen8_fs_generator uses these to decide whether to set the execution size
to 8 or 16, so we incorrectly made both of these MOVs the full width in
SIMD16 shaders.  (It happened to work out on Gen4-7.)

Setting them should also help inform optimization passes what's really
going on, which could help avoid bugs.

cb04294b42 i965: Set execution size to 8 for instructions with force_sechalf set.
Both inst->force_uncompressed and inst->force_sechalf mean that the
generated instruction should be uncompressed and have an execution size
of 8.  We don't require the visitor to set both flags - setting
inst->force_sechalf by itself is supposed to be enough.

On Gen4-7, guess_execution_size() demoted instructions to 8-wide based
on the default compression state.  On Gen8+, we instead set a default
execution size, which worked great...except that we forgot to check
inst->force_sechalf when deciding whether to use 8 or 16.

Kernels which have attributes can have more than 1, e.g.:
!0 = metadata !{void (i32 addrspace(1)*)* @testKernel, metadata !1}
!1 = metadata !{metadata !"work_group_size_hint", i32 4, i32 1, i32 1}

Attempting to get the kernel without the correct number of attributes led
to memory corruption and luxrays crashing out.

3ca2119593 glxext: Send the Drawable's ID in the GLX_BufferSwapComplete event
While the official INTEL_swap_event specification says that the drawable
field should contain the GLXDrawable, not the Drawable, the existing
DRI2 code in dri2.c that translates from DRI2_BufferSwapComplete sends out
GLX_BufferSwapComplete with the Drawable's ID, so existing codebases
like Clutter/Cogl rely on getting the Drawable.

Match DRI2's error here and stuff the event with the X Drawable, not
the GLX drawable.

This fixes apps seeing wrong drawables through an indirect GLX context
or with DRI3, which uses the GLX_BufferSwapComplete event directly on
the wire instead of translates Present in mesa.

At the same time, also modify the structure for the event to make sure
that clients don't make the same mistake. This is not an API or ABI
break, as GLXDrawable and Drawable are both typedefs for XID.

The right viewport index would not be set on the primitive because the
last vertex is the provoking one. However blob drivers appear to move
the gl_ViewportIndex write into the for loop, allowing the application
to be ignorant of this detail.

While the application is technically wrong here, because the blob does
it and other drivers appear to implicitly work this way as well, we add
a buffer register that viewport index writes go into, which is then
exported before every EmitVertex() call.

This fixes the remaining piglit tests in ARB_viewport_array for nv50/nvc0.

6ae4aff303 draw: (trivial) fix clamping of viewport index
The old logic would let all negative values go through unclamped, with
potentially disastrous results (probably trying to fetch viewport values
from random memory locations). GL has undefined rendering for vp indices
outside valid range but that's a bit too undefined...
(The logic is now the same as in llvmpipe.)

500849f9cf i965: Don't emit SURFACE_STATEs for gather workarounds on Broadwell.
As far as I can tell, Broadwell doesn't need any of the SURFACE_STATE
workarounds for textureGather() bugs, so there's no need to emit
a second set of identical copies.

To keep things simple, just point the gather surface index base to the
same place as the texture surface index base.
