GLSL says that indexing in a samplers array should be done with
a dynamically uniform value.
If the app doesn't obey this constraint, it'll get incorrect
results.
But there's one case where the app might be correct and yet
get incorrect result: if 2 consecutive draws are used, with no
state changes in between, the hardware might run them in the
same wave and the app will get incorrect result as-if it was
using non-dynamically uniform index.
To prevent this, this commit takes advantage of the divergence
analysis pass - if the index is marked as divergent, then it will
have the same effect as using ACCESS_NON_UNIFORM in SPIR-V.

In some scenario ac_init_llvm_target may be called twice,
but the LLVM library won't have been unloaded between
the 2 calls, leading to a LLVM warning being printed.
Example pseudo-code to trigger this for radeonsi:
gbm_create_device();
eglInitialize();
eglTerminate();
gbm_device_destroy();
gbm_create_device();
eglInitialize();
eglTerminate();
gbm_device_destroy();
To avoid the warning message from LLVM, clear the command line
parser state before calling LLVMParseCommandLineOptions.
This might fix https://gitlab.freedesktop.org/mesa/mesa/-/issues/5960
This is done only on LLVM 12+ because it seems to break some apps
on LLVM 11 (there has been some work post LLVM 11 release to refactor
CommandLine.cpp, see 42f588f39c5c and the following commits).

This method isn't part of the C API but we can still use it and
avoid getting error messages from the command line parser:
mesa: for the [...]: may only occur zero or one times
We could call it at the beginning of ac_init_llvm_target but
this may hide some real bugs so let drivers call it.

Now, control_barrier shouldn't add any waits because memory_barrier is
responsible for it, so remove the wait.
