Revert "i965: Drop the maximum 3D texture size to 512 on Sandy Bridge"

This reverts commit 6ba88bce64b343761aabe3a6c7ee285c6020a959.  The commit
was erroneous because GL has a separate limit, GL_MAX_FRAMEBUFFER_LAYERS
which guards the number of layers you are allowed to render into.

The GL 4.5 spec says:

   "The framebuffer attachment point attachment is said to be framebuffer
   attachment complete if [...] all of the following conditions are true:

      [...]

      If image is a three-dimensional, one- or two-dimensional array, or
      cube map array texture and the attachment is layered, the depth or
      layer count of the texture is less than or equal to the value of the
      implementation-dependent limit MAX_FRAMEBUFFER_LAYERS."

and goes on to say that "framebuffer complete" requires all attachments to
be "framebuffer attachment complete".

On Sandy Bridge, we set GL_MAX_FRAMEBUFFER_LAYERS to 512 so creating a 3D
texture bigger than 512 is fine; you just can't render into all of the
slices at once.

nir/gcm: Add global value numbering support

Unlike the current CSE pass, global value numbering is capable of detecting
common values even if one does not dominate the other.  For instance, in
you have

if (...) {
   ssa_1 = ssa_0 + 7;
   /* use ssa_1 */
} else {
   ssa_2 = ssa_0 + 7;
   /* use ssa_2 */
}

Global value numbering doesn't care about dominance relationships so it
figures out that ssa_1 and ssa_2 are the same and converts this to

if (...) {
   ssa_1 = ssa_0 + 7;
   /* use ssa_1 */
} else {
   /* use ssa_1 */
}

Obviously, we just broke SSA form which is bad.  Global code motion,
however, will repair this for us by turning this into

ssa_1 = ssa_0 + 7;
if (...) {
   /* use ssa_1 */
} else {
   /* use ssa_1 */
}

This intended to eventually mostly replace CSE.  However, conventional CSE
may still be useful because it's less of a scorched-earth approach and
doesn't require GCM.  This makes it a bit more appropriate for use as a
clean-up in a late optimization run.

r300g: Set R300_VAP_CNTL on RSxxx to avoid triangle flickering

On the RSxxx chip series, HW TCL is missing and r300_emit_vs_state()
is never called.

However, if R300_VAP_CNTL is never set, the hardware (at least the
RS690 I tested this on) comes up with rendering artifacts, and
parts that are uploaded before this "fix" remain broken in VRAM.
This causes artifacts as in fdo#69076 ("triangle flickering").

It seems like this setup needs to happen at least once after power on
for 3D rendering to work properly. In the DDX with EXA, this happens in
RADEON_SWITCH_TO_3D() when processing an XRENDER Composite or an
Xv request. So playing back a video or starting a GTK+2 application
fixes 3D rendering for the rest of the session. However, this auto-fix
doesn't happen when EXA is not used, such as with GLAMOR or Wayland.

This patch ensures the register is configured even in absence of
the DDX's EXA module.

The register setting is taken from:
  xf86-video-ati  --  RADEONInit3DEngineInternal()
  mesa/src/mesa/drivers/dri/r300  --  r300EmitClearState()

Tested on RS690.
