nouveau: allow NV3x's to be used with nouveau_vieux

NV34 and possibly other NV3x hardware has the capability of exposing the
NV25 graph class. This allows forcing nouveau_vieux to be used instead
of the gallium driver, primarily for testing purposes. (Among other
things, NV2x only ever came as AGP or inside an Xbox, never PCI/PCIe).

svga: fix a texture readback bug

Backing views/surfaces are used to handle the case when a resource is
bound both as a render target and as a sampler source (such as when
doing auto mipmap generation).

This patch fixes a bug where mapping a resource (to do a glReadPixels)
was reading the stale data in the original surface rather than the
backing surface which was rendered to.

We need to propagate the backing resource (which we rendered to) back
to the original resource before we read from it.  The problem was the
svga_propagate_rendertargets() function was examining the wrong surface
views.

This fixes the "poc9" test described in VMware bug 1686661.
Also tested with Piglit, Cinebench, Lightsmark, etc.

it through the blorp_context.  When we start using blorp in Vulkan, we will

Note: In my first attempt at this, I simplified it down to a single
upload_shader entrypoint and implemented the caching inside of blorp.  This
doesn't work, however, because the i965 driver will, on occation, dump its
entire cache and start over.  When this happens, blorp needs to be able to
recompile its shaders and re-upload them.  It's easiest to just expose the
caching interface.

i965/vec4: remove the generator hack for dual instanced GS

This hack was introduced in commit 03ac2c7223f7645e3:
i965/gs: Fix up gl_PointSize input swizzling for DUAL_INSTANCED gs

Specifically to fixup the code we emitted to deal with gl_PointSize inputs
in dual instance mode, where we were emitting a MOV to copy the point
size from .w (where the hardware delivers it) to .x (because code will
expect this to be a float). This meant that we were emitting a MOV
to an ATTR destination that could have a width of 4 (in dual instanced
mode) so it was necessary to fix the execution size and regioning of the
instruction.

Fortunately, Ken fixed this in 67c5d00273ca2:
i965/vec4/gs: Stop munging the ATTR containing gl_PointSize.

by using a WWWW swizzle instead of a MOV, and as the commit log in that
patch states, we no longer emit instructions with ATTR destinations, so
that makes the fixup code in the generator unnecessary.

mesa: remove OES_shader_io_blocks enable

This extension should just be available whenever ES 3.1 is available.
With the new extension verification infrastructure, it will only be
enable-able on a #version 310 es shader, rendering the original reason
for having a separate enable moot.

i965: Enable OES_texture_cube_map_array on Gen8+

These are the only platforms that current expose OES_geometry_shader.
Once OpenGL ES 3.1 and OES_geometry_shader are enabled on Gen7, this
extension can be enabled there as well.

Gen6 will never get OpenGL ES 3.1, so it will never get this
extension... even though it has the desktop OpenGL extension.  Alas.

NOTE: This causes a failure on Gen8+ platforms in
ES3-CTS.gtf.GL3Tests.texture_storage.texture_storage_texture_targets.
The test only fails because it doesn't know that 0x9009 is a valid
value when the extension exists.
