Graph/Update/dyn_cgf_accessor_spv.cpp and Graph/Explicit/regression_accessor_spv.cpp sporadic fail on Linux BMG

### Describe the bug

Graph/Update/dyn_cgf_accessor_spv.cpp is sporardically failing on Linux BMG.

It may be with the SPIR_V backend only (lit param ` --param spirv-backend=True` but I'm disabling it in general to be safe.
