In the past, BLORP has clobbered all BRW_NEW_* state flags, to trigger
re-emission of the entire 3D pipeline on the next draw. However, there
are some packets BLORP simply leaves alone, so there's no need to
re-emit them. Trying to reduce the set of dirty bits flagged after
BLORP runs is tricky.
Instead, we introduce a BRW_NEW_BLORP flag. This should be set on any
atom which emits a packet that BLORP also emits. When BLORP runs, it
will flag BRW_NEW_BLORP, causing those packets to get re-emitted.
This also makes it easy to avoid re-emitting specific atoms - we can
simply drop the BRW_NEW_BLORP flag on those.
To start, we assume that all packets need to be re-emitted. This is the
safest approach and closest to the existing code's behavior. Many of
these are obviously not required, and can be dropped in subsequent
patches.
