PTB assumes that base instance to be 0 at start of tile, but hw would not do that, we need to set it. It is worth to note that the opcode name is somewhat confusing as what it really sets is the base instance. We could rename the opcode, but then the name would be different to the original Broadcom name, so confusing in any case. This fixes several dEQP-GLES3 and dEQP-GLES31 tests that passes individually, but started to fail depending on other tests running before using base instance different to zero. This is the backport of a Vulkan patch that fixed some Vulkan CTS tests that start to fails after some other tests used an instance id.
