anv: Implement VK_EXT_conditional_rendering for gen 7.5+
Conditional rendering affects next functions: - vkCmdDraw, vkCmdDrawIndexed, vkCmdDrawIndirect, vkCmdDrawIndexedIndirect - vkCmdDrawIndirectCountKHR, vkCmdDrawIndexedIndirectCountKHR - vkCmdDispatch, vkCmdDispatchIndirect, vkCmdDispatchBase - vkCmdClearAttachments Value from conditional buffer is cached into designated register, MI_PREDICATE is emitted every time conditional rendering is enabled and command requires it. v2: by Jason Ekstrand - Use vk_find_struct_const instead of manually looping - Move draw count loading to prepare function - Zero the top 32-bits of MI_ALU_REG15 v3: Apply pipeline flush before accessing conditional buffer (The issue was found by Samuel Iglesias) v4: - Remove support of Haswell due to possible hardware bug - Made TMP_REG_PREDICATE and TMP_REG_DRAW_COUNT defines to define registers in one place. v5: thanks to Jason Ekstrand and Lionel Landwerlin - Workaround the fact that MI_PREDICATE_RESULT is not accessible on Haswell by manually calculating MI_PREDICATE_RESULT and re-emitting MI_PREDICATE when necessary. v6: suggested by Lionel Landwerlin - Instead of calculating the result of predicate once - re-emit MI_PREDICATE to make it easier to investigate error states. v7: suggested by Jason - Make anv_pipe_invalidate_bits_for_access_flag add CS_STALL if VK_ACCESS_CONDITIONAL_RENDERING_READ_BIT is set. v8: suggested by Lionel - Precompute conditional predicate's result to support secondary command buffers. - Make prepare_for_draw_count_predicate more readable.
