V3D 4.x allows more flexibility, so take advantage of that. Generally,
we can reorder any writes in the same sequence, so long as they are
not the sequence terminator (which must always be last, since it is
the one triggering the operation), and TMUD writes, since these must
be ordered with respect to each other.

Instead of using a write depdency. We use last_tmu_config to ensure ordering
of instructions participating in different TMU sequences. To this end,
all sequence terminators flag a write dependency on last_tmu_config, but
wrtmuc is not a sequence terminator, so we can be more flexible by flagging
it as a read depedency. This would prevent it to be moved into a previous
sequence (since it cannot be moved past the previous sequence terminator due
to the read depedency), but it allows it to be reordered with instructions in
the same sequence, which allows us to pair it up more effectively. Particularly,
it allows to pair up a wrtmuc with the sequence terminator of the same sequence,
turning code like this:
nop ; mov tmut, r0 ; thrsw; wrtmuc (tex[0].p0 | 0x3)
nop ; nop ; wrtmuc (tex[0].p1 | 0x0)
nop ; mov tmus, r1
Into this:
nop ; mov tmut, r0 ; thrsw; wrtmuc (tex[0].p0 | 0x3)
nop ; mov tmus, r1 ; wrtmuc (tex[0].p1 | 0x0)

The disadvantages of the DYNAMIC path over the
non-dynamic path are minor.
The advantages are many.
As we don't know if bad behaving apps use
non-dynamic SYSTEMMEM in a dynamic fashion,
let's be safe and always be dynamic.

SW vertex processing buffers are supposed to be sorted in RAM
and to be immediately idle after use (thus you can write at the
same location again immediately).
DYNAMIC SYSTEMMEM is by far the best fit for now for these kind
of buffers, though it can be improved further. Indeed the use
pattern will cause a lot of syncs with csmt actived.
Thus disable csmt when full sw vertex processing is requested.

Some apps use DYNAMIC SYSTEMMEM buffers and fill them in a
dynamic fashion with discard and nooverwrite locking flags.
To prevent uploading the whole buffer every draw call,
track the region needed for the draw call, and
upload only that region (or a bit more in order
to ease valid region tracking).
Try to aggressively upload with discard/unsynchronized.
