This includes setting the correct end point of the propagation and
not propagating the incoming values after the loop header.
This patch also changes the propagation to a single iteration for
loop exit phis.

Offical naming of Mali GPUs is like Mali-G52 or Mali-T860 wth a dash.
Also variants of the same GPU e.g. revision 1 are generally not part
of the name. This adds a dash instead of a space between Mali and the
model and also splits off the r1 revision with a space. This should
keep the naming in-line with offical names and with what the binary
DDK uses for naming.

This is the last step before we can start removing the history flush
mechanism: In cases where a dirtied buffer has the potential to be
concurrently bound to the pipeline (as indicated by the bind_history
mask), flag the "flush" dirty bits corresponding to its binding point.
This ensures that the buffer-local memory barriers introduced earlier
in this series are executed before the next draw call, which in turn
will emit any necessary PIPE_CONTROLs in cases where the buffer is
bound through a cache incoherent with the cache that performed the
write.

This adds buffer-local barriers so any required synchronization
commands are emitted before a buffer object is used as source for
indirect draw parameters. An unconditional PIPE_CONTROL meant to
flush the contents of the draw count buffer can now be removed, since
it's redundant with the more accurate buffer-local barrier introduced
here, which should avoid flushing in cases where the buffer wasn't
written by any incoherent cache since the last flush.

This ensures that any required synchronization (i.e. PIPE_CONTROL)
commands are emitted whenever a vertex or index buffer is used in
cases where it had been previously accessed from an incoherent caching
domain.

This will allow us to order writes and reads of vertex and index
buffers by using the same cache tracking infrastructure introduced
previously for render and depth buffers. The ultimate goal is to
remove the somewhat heavy-handed history flush mechanism currently
used for buffer objects, and use a single cache tracking mechanism
across the whole driver.
v2: Use C99 designated initializers (Ken).

For blob_mem allocated from virtgpu_virgl backend, the guest mappable
size queried can be smaller than the size returned from image memory
requirement query from the host side. Here we temporarily workaround
until we switch to use cross-domain backend in minigbm.

We're moving away from relying on the Kernel's implicit busy tracking
into our own tracking, except for shared buffers.
Not only this shouldn't hurt now (it doesn't, according to my
measurements), when we switch to vm_bind we will be able to cut some
significant overhead by simply omitting all the async buffers from the
execbuf ioctl.
v2:
- Change iris_bo_busy() to bool (Ken).
- Fix coding style issues (Ken).
- Rebase on not having the refcount _inc and _dec helpers anymore
(Ken).

We want to implement explicit BO dependency tracking and for that
we'll use arrays of dependencies (syncobjs) indexed by screen->id.
This is way more efficient than storing and checking screen pointers
everywhere.

The next patches will justify the new ownership. We want the BOs to
have references on the batches' syncobjs so we can implement implicit
tracking. In other words: BOs will be able to wait on syncobjs owned
by different screens. Since our syncobjs are actually just a Kernel
handle with a refcount, they can be used globally and it makes more
sense to map them to the bufmgr, just like the BOs.

This is the first part of a refactor to make vertex compaction optional.
Additionally, it may yield a very small benefit to allocate the PC
space sligtly sooner.
