As per this optimisations description:
"Takes assignments to variables that are dereferenced only
once and pastes the RHS expression into where the variables
dereferenced."
However the optimisation is run at compile time before multiple
shaders from the same stage could have been pasted together.
So this optimisation can incorrectly assume a global is only
referenced once since it cannot see the other pieces of the
shader stage until link time.
Here we skip the optimisation if the variable is a global. We
could change it to only run at link time however this
optimisation is only run at link time if we are being forced
to use GLSL IR to inline a function that glsl to nir cannot
handle and this will also be removed in a future patchset.

Similar to what was done for Wayland in 58f90fd03f:
the glthread unmarhsal thread needs to be idle to avoid
concurrent calls to get_back_bo.
Also the existing code flushed after setting dri2_surf->back
to NULL so a new back buffer was always allocated by the
glthread flush:
|---------------> dri2_drm_swap_buffers
| get_back_bo (back=0x55eb93c6c488) > # First get_back_bo call
| get_back_bo (back=0x55eb93c6c488 age: 0)<
| # dri2_surf->back = NULL
|-----> FLUSH
| get_back_bo (back=nil) > # Another get_back_bo call
| get_back_bo (back=0x55eb93c6c4c8 age: 3)<
|-----< FLUSH
|---------------< dri2_drm_swap_buffers

GL ARB_sparse_buffer allows unbound regions in buffers.
VK sparseBinding insists all regions must be bound before first use.
This means we need to use sparseResidencyBuffer to back GL
sparse buffers to get the same semantics.

LLVM_LIB_DIR is a variable used for runtime compilations.
When cross compiling, LLVM_LIB_DIR must be set to the
libclang path on the target. So, this path should not
be retrieved during compilation but at runtime.
dladdr uses an address to search for a loaded library.
If a library is found, it returns information about it.
The path to the libclang library can therefore be
retrieved using one of its functions. This is useful
because we don't know the name of the libclang library
(libclang.so.X or libclang-cpp.so.X)

(cherry picked from commit 445aacb421)
If the lane from which the hardware writes the unifa address
is disabled, then we may end up with a bogus address and invalid
memory accesses from follow-up ldunifa.
Instead of always disabling unifa loads in non-uniform control
flow we can try to see if the address is prouced from a nir
register (which is the only case where we do conditional writes
under non-uniform control flow in ntq_store_def), and only
disable it in that case.
When enabling subgroups for graphics pipelines, this fixes a
GMP violation in the simulator with the following test
(which has non-uniform control flow writing unifa with lane 0
disabled, which is the lane from which the unifa takes the
address):

descriptor buffer uses mapped buffers. mapping/unmapping buffers

since the ctx is not actually used for unmapping descriptor buffers,
this can instead use a special buffer unmap function to avoid invalid access

This fixes#9807 but I don't understand why.
Emitting cache flushes before VGT_PRIMITIVE_TYPE is what makes
the problem go away but changing the order in si_draw() is clearer.
The only cases where sctx->flags is modified in si_emit_draw_registers
is handled using si_emit_cache_flush_direct so we can move cache
flushing up without any addtional conditionals.

When updating an AFBC-packed resource, we need to make sure it is
legalized before blitting the staging resource to it. We can't rely
on the blit to properly convert the resource as it will result in
blit recursion and a crash.
If the whole texture is updated however, there is no need to unpack
as the content can be discarded. Just create a new BO with the right
format.
