An issue similar occurs when running Civ6 on Virgl. Is there any to disable
TGSI indirect indexing for testing purposes?

Connor, the hardware manages the scratch buffer alloc/dealloc. You don't have
to allocate more than one.
The problem with Civ VI is that VGPR indexing has never been properly
implemented for gfx9 in LLVM.

After talking this over with Marek here is a summary of the problem.
LLVM's VGPR indexing code on gfx9+ is broken for immediate arrays. Usually this
is not a problem as GLSL IR in mesa will lower these to
