radeonsi: add GS multiple streams support (v2)
This is the final piece for ARB_gpu_shader5, The code is based on the r600 code from Glenn Kennard, and myself. While developing this, I'm not 100% sure of all the calculations made in the GS registers, this is why the max_stream is worked out there and used to limit the changes in registers. Otherwise my initial attempts either regressed GS texelFetch tests or primitive-id-restart. The current code has no regressions in piglit. This commit doesn't enable ARB_gpu_shader5, since that just bumps the glsl level to 4.00, so I'll just do a separate patch for 4.10. v1.1: fix bug introduced in rebase. v2: Address Marek's review comments, remove my llvm stream code for simpler C, move gsvs_ring and gs_next_vertex to arrays.
