nir: Add new GS intrinsics that maintain a count of emitted vertices.
This patch also introduces a lowering pass to convert the simple GS intrinsics to the new ones. See the comments above that for the rationale behind the new intrinsics. This should be useful for i965; it's a generic enough mechanism that I could see other drivers potentially using it as well, so I don't feel too bad about putting it in the generic code. v2: - Use nir_after_block_before_jump for the cursor (caught by Jason Ekstrand - I'd mistakenly used nir_after_block when rebasing this code onto the new NIR control flow API). - Remove the old emit_vertex intrinsic at the end, rather than in the middle (requested by Jason). - Use state->... directly rather than locals (requested by Jason). - Report progress from nir_lower_gs_intrinsics() (requested by me). - Remove "Authors:" section from file comment (requested by Michael Schellenberger Costa).
