It appears that flushing the DB metadata is actually not sufficient
since the driver uses the new VS blit shaders. This looks quite
strange though, but it seems like we need to flush DB for fixing
the corruption.

Because vc4 can control the order that tiles are rasterized in, we can use
it to implement overlapping blits using normal drawing and
GL_ARB_texture_barrier, as long as we can tell the kernel what order to
render the tiles in.
This commit introduces the core gallium support, vc4 changes will follow.
v2: Fix on the simulator.
v3: Add the cap (disabled) to other drivers, add rst docs for the cap.
v4: Rebase on PIPE_CAP_TGSI_ANY_REG_AS_ADDRESS
v5: Drop vc4 changes from this commit, for clarity.

Our driver implementation is known to decrease performance for some tests,
but we don't know if any apps and benchmarks (e.g. those tested by Phoronix)
are affected. This disables the feature just to be safe.
Set this to enable partial primitive binning:

Note: this causes spurious regressions in some current piglit tests,
because the tests incorrectly assume that there is no denorm support for
doubles. I'm going to send out a fix for those tests as well.

This marks the end of code sharing between r600 and radeonsi.
It's getting difficult to work on radeonsi without breaking r600.
A lot of functions had to be renamed to prevent linker conflicts.
There are also minor cleanups.

We do not enable this by default for additive blending, since it slightly
breaks OpenGL invariance guarantees due to non-determinism.
Still, there may be some applications can benefit from white-listing
via the radeonsi_commutative_blend_add drirc setting without any real
visible artifacts.

This option enables a performance optimization where typical non-blending
draws with depth buffer may be rasterized out-of-order (on VI+, multi-SE
chips).
This optimization can lead to incorrect results when an applications
renders multiple objects with the same Z value at the same pixel, so we
will never enable it by default. But there may be applications that could
benefit from white-listing.

Using VRAM address as bindless handles is not a good idea because
we have to use LLVMIntToPTr and the LLVM CSE pass can't optimize
because it has no information about the pointer.
Instead, use slots indexes like the existing descriptors. Note
that we use fixed 16-dword slots for both samplers and images.
This doesn't really matter because no real apps use image handles.
This improves performance with DOW3 by +7%.
