r600: increase performance for DRI PRIME offloading if 2nd GPU is Evergreen+
This is a direct port of Marek Olšáks patch
"radeonsi: increase performance for DRI PRIME
offloading if 2nd GPU is CIK or VI" to r600.
It uses SDMA for the detiling blit from renderoffload VRAM
to GTT, as SDMA is much faster for tiled->linear blits from
VRAM to GTT.
Testing on a dual Radeon HD-5770 setup reduced the time
for the render offload gpu to get its rendering into
system RAM from approximately 16 msecs for simple rendering
at 1920x1080 pixel 32 bpp to 5 msecs, a > 3x speedup!
This was measured using ftrace to trace the time the radeon kms
driver waited on the dmabuf fence of the renderoffload gpu to
complete.
All in all this brought the time for a flip down from 20 msecs
to 9 msecs, so the prime setup can display at full 60 fps instead
of barely 30 fps vsync'ed.
The current r600 implementation supports SDMA on Evergreen and
later, but not R600/R700 due to some bugs apparently present
in their SDMA implementation.

i965/gen7: Add R8_UINT stencil miptree copy for sampling
For gen < 8, we can't sample from the stencil buffer, which is
required for the ARB_stencil_texturing extension. We'll make a copy of
the stencil data into a new texture that we can sample using the
R8_UINT surface type.

i965/hsw: Don't advertise more than 64 threads for compute shaders
thread_width_max in the GPGPU walker command limits us to a maximum of
64 threads.
This fixes a crash on Haswell in the OpenGLES 3.1 conformance test
suite which tests the advertised limits of the max invocation counts.

radeonsi: increase performance for DRI PRIME offloading if 2nd GPU is CIK or VI
SDMA is much faster for tiled->linear blits from VRAM to GTT.
I have Bonaire in my second PCIe slot.
$ glxinfo | grep OpenGL.renderer
OpenGL renderer string: Gallium 0.4 on AMD TONGA ...
$ DRI_PRIME=1 glxinfo | grep OpenGL.renderer
OpenGL renderer string: Gallium 0.4 on AMD BONAIRE ...
Without SDMA:
$ DRI_PRIME=1 glxgears
8796 frames in 5.0 seconds = 1759.074 FPS
8899 frames in 5.0 seconds = 1779.672 FPS
With SDMA:
$ DRI_PRIME=1 glxgears
12765 frames in 5.0 seconds = 2552.788 FPS
12888 frames in 5.0 seconds = 2577.495 FPS
The 1st GPU is irrelevant. The improvement should be much lower at 60 fps,
but definitely measurable.
SI will get this once we add SDMA blit support for it.
