This is the core of ARB_texture_multisample. Most of the piglit tests for
GL_ARB_texture_multisample require GL 3.0, but exposing support for this
lets us use the gallium blitter for multisample resolves. We can
sometimes multisample resolve using just the RCL, but that requires that
the blit is 1:1, unflipped, and aligned to tile boundaries.
This includes GL_SAMPLE_COVERAGE, GL_SAMPLE_ALPHA_TO_ONE, and
GL_SAMPLE_ALPHA_TO_COVAGE.
I haven't implemented a dithering function yet, and gallium doesn't give
me a good chance to do so for GL_SAMPLE_COVERAGE.
I only stumbled on this while experimenting due to reading about HW-2905.
I don't know if the EZ disable in the Z-clear is actually necessary, but
go with it for now.
The recent unaligned fix successfully prevented RCL blits that weren't
aligned inside of the surface, but we also want to be able to do RCL blits
for the whole surface when the width or height of the surface aren't
aligned (we don't care what renders inside of the padding).
For some reason this has been disabled for integers ever since codegen
was merged, despite there being emission code for IMAD. Seems to work.

According to nvdisasm both the immediate and non-imm cases use the same
bits. Both of these flags are quite rarely set though.

We actually leave the sampler unset for OP_TXF, which caused the GK104+
logic to treat some texel fetches as indirect. While this works, it's
incredibly wasteful. This only happened when the texture was > 0 (since
sampler remained == 0).

The workarounds are too hacky to enable them by default
and otherwise MPEG4 doesn't work reliably.

Use the new debug callback hook to report conformance, performance
and fallbacks to the state tracker. The state tracker, in turn can
report this issues to the user via the GL_ARB_debug_output extension.
More issues can be reported in the future; this is just a start.
v2: remove conditionals around pipe_debug_message() calls since the
check is now done in the macro itself.
v3: remove unneeded dummy %s substitutions

At last on ARUBA this is required to stop tessellation hanging
in heaven.
This removes one of the SIMDs from use by the HS/LS.

This adds the streamout and export workarounds to TES,

When we are finished the shader, we read back all the tess factors
from LDS and write them to special global memory storage using

TCS outputs whenever they are written in the shader,
need to be written to LDS not temporaries, this handles
this case. It also fixes up the case where the output

When using tessellation on eg/ni chipsets, we must disable
dynamic GPRs to workaround a hw bug where the GPU hangs
when too many things get queued.
This implements something like the r600 code to emit
the transition between static and dynamic GPRs, and to
statically allocate GPRs when tessellation is enabled.
