 * When this SHOULD NOT be used:
 *
 * - if si_context_add_resource_size has been called for the buffer
 *   followed by *_need_cs_space for checking the memory usage
 *
 * - if si_need_dma_space has been called for the buffer
 *
 * - when emitting state packets and draw packets (because preceding packets
 *   can't be re-emitted at that point)
 *
 * - if shader resource "enabled_mask" is not up-to-date or there is
 *   a different constraint disallowing a context flush
