https://reviews.llvm.org/rL356946 (present in LLVM 9 and later) changed
the meaning of the "system" sync scope, making it no longer restricted to
the memory operation's address space. So a single address space sync scope
is needed for shared atomic operations (such as "system-one-as" or
"workgroup-one-as") otherwise buffer_wbinvl1 and s_waitcnt instructions
can be created at each shared atomic operation.
This mostly reimplements LLVMBuildAtomicRMW and LLVMBuildAtomicCmpXchg
to allow for more sync scopes and uses the new functions in ac->nir with
the "workgroup-one-as" or "workgroup" sync scopes.

To quote Uli Schlachter, who understands this stuff more than I do:

`__glXSendErrorForXcb` was also patched, as that's the function that
`glXCreateContextAttribsARB` actually uses.

In commit 0d46e404 ("anv: limit URB reconfigurations when using
blorp") we tried to limit the number of URB reconfiguration by
checking if the last allocation is large enough to fit the blorp
dispatch.
We used the last bound pipeline to compare the allocation. The problem
with this is that the pipeline is bound but its commands might not
have been emitted into the command buffer yet.
Let's just revert commit 0d46e40467
since it didn't seem to yield any performance improvement.

It's prefectly legal and well-defined to render using a non-existing
or empty buffer object. The data coming out of the buffer object isn't
well defined unless we have the robustness flag set on the context, but
that's a different matter, and up to the shader hardware; it's the same
as out-of-bounds reads.

This patch switches the order of the conditionals in swr_update_derived,
so the logic becomes a bit more straight forward:
if (is_user_buffer)

...instead of this:

From page 76 (page 80 of the PDF) of the GLSL 4.60 v.5 spec:
" No aliasing in output buffers is allowed: It is a compile-time or
link-time error to specify variables with overlapping transform
feedback offsets."
Currently, this is expected to fail, but it succeeds:
"
...

layout (xfb_offset = 0) out vec4 b;

gl_FragCoord.w = 1.0 / gl_FragCoord_orig.w

In a perfect world, we'd use fp16 varyings for mediump and fp32 for

Some of the dEQP.functional.transform_feedback tests end up doing
the following sequence of operations:
1. BeginTransformFeedback
2. PauseTransformFeedback
3. Draw
4. ResumeTransformFeedback
At step 1, we'd pack 3DSTATE_SO_BUFFER commands saying to zero the
SO_WRITE_OFFSET registers. At step 2, we disable streamout, so step 3
doesn't bother emitting those commands. Then, step 4 re-packs new
3DSTATE_SO_BUFFER commands with offset = 0xFFFFFFFF, saying to continue
appending at the existing offset. This loads the value from the BO as
the offsets - but we never actually zeroed it.
So, just maintain a flag saying "we actually emitted the commands",
and stomp offset back to zero until we emit some.

We are assured that the input segment size field is ignored for
