The app is allowed to never bind descriptor sets that are statically
unused by the pipeline, which would've caused a context fault since
CP_LOAD_STATE6 would try to load the descriptors that don't exist. Fix
this by not preloading descriptors from unused descriptor sets. We could
do more fine-grained accounting of which descriptors are used, but this
is enough to fix the problem.

Unreal Engine 4 has a bug in usage of glDrawRangeElements,
causing it to be called with a number of vertices in place
of "end" parameter (which specifies the maximum array index
contained in indices).
Since there is unknown amount of games affected and we
could not identify that a game is built with UE4 - we are
forced to make a blanket workaround, disregarding max_index
in range calculations. Fortunately all such calls look like:
glDrawRangeElements(GL_TRIANGLES, 0, 3, 3, ...);
So we are able to narrow down this workaround.
This was uncovered after b684030c3a
broke a bunch of UE4 games.

Replace the various ad-hoc flushes that we've inserted, copied from
freedreno, etc. with a unified system that uses the user-supplied
information via vkCmdPipelineBarrier() and subpass dependencies.
There are a few notable differences in behavior:
- We now move setting RB_CCU_CNTL up a little in the gmem case, but
hopefully that won't matter too much. This matches what the Vulkan blob
does.
- We properly implement delayed setting of events, completing our
implementaton of events.
- Finally, of course, we should be a lot less flush-happy. We won't emit
useless CCU/cache flushes with multiple copies, renderpasses, etc. that
don't depend on each other, and also won't flush/invalidate the cache
around renderpasses unless we actually need to.

We just dropped the last user which actually cared about the seqno.
This never worked anyway, since the seqno was never reset between
multiple executions of the same command buffer. Turn the part of the
control buffer which used to track the seqno into a dummy dword, and
figure out automatically whether we need to include it. We will
implement seqnos again eventually, with timline semaphores, but that
will likely be totally different.

The Vulkan blob doesn't do this, and based on my understanding of how
the blob works this is unnecessary. CACHE_FLUSH is already serialized
against all 3d commands so you don't need to wait for rendering commands
to finish before issuing it, and the subsequent wfi + WAIT_FOR_ME will
cause the CP to wait for the CACHE_FLUSH to finish, so there's also no
need to wait for it to complete. The CACHE_INVALIDATE also seems
unnecessary, and also isn't done by the blob.

The current "ds = state->bs" seems broken, and the "vs = state->bs" is
unnecessary (already set above). Since it was added as part of a GS-related
patch, I think this is what was intended.
Note: tesselation disables GMEM rendering so we shouldn't have to worry
about hs/ds + binning interaction.

asin(x) is now implemented using a piecewise approximation, which
improves the precision for |x| < 0.5
Previously, we were using a polynomial approximation for both the
asin() and acos() functions. Unfortunately, for asin(), this polynomial
does not have enough precision to satisfy the Vulkan CTS requiremenents,
which define the asin() precision based on the precision of
atan2(x, sqrt(1.0 - x*x)). The piecewise approximation gives the needed
precision in the problematic range.
v2: Skip the piecewise approximation for acos

Tessellation shader in llvmpipe depends on llvm coroutines support. So do not
advertise tessellation shader support in llvmpipe if GALLIVM_HAVE_CORO is FALSE.
This fixes assertion in LLVMTokenTypeInContext() running tessellation shader
tests with llvm version < 6.
