-1 is used to select "choose the dest type", but we were dereffing src[-1]
anyway and the compiler is not a fan.

Avoid having to mmap() unnecessarily by moving UBWC clear/init to
blitter.
Because we don't have a context when the bo is allocated, we need to
lazily initialize UBWC data, so hook into the resource_written()
tracking to do this. Don't bother with resource_read() because that
would be undefined anyways.

For prologue's in the nondraw path, we need a "gmem" rb that we can emit
the IB to the prologue before the main part of the batch. This has the
side benefit of cleaning up a bunch of duplicate setup code in a5xx.

Replace lrz_clear with the more general purpose prologue rb. While the
epilogue is per-tile (in gmem mode), the prologue is per-batch, so also
add some comments to make that point more clear.

Having panfrost_batch access the pan_pool fields directly makes it hard
to change pan_pool internals, like for instance, changing the hash table
for a dynamic array. Let's hide pan_pool internals behind helpers that do
what we need.

_create functions usually allocate an object and return a pointer to the
allocated object, _init ones usually take an existing object and
initialize it. Let's follow this semantic here by renaming the
panfrost_create_pool() function and updating its prototype.

Again, we'd like to keep the routines filling out the postfix together,
and this has a single remaining caller (once for vertex then immediately
for tiler).
By keeping them together we can avoid uploading the shared
memory/framebuffer structures twice in a row, saving a bit of memory in
the process.
We also fix a bug where bit 2 of gl_enables is incorrectly set on
Bifrost.

Given we emit shared memory immediately after anyway, the function call
doesn't do anything but zero-initializing the payload and setting some

Need to signal push constants via a side channel. I tried to disentangle
this code, but there are a number of stacked issues here:
* We need to upload sysvals. Currently we prefix UBO #0 with sysvals,
but this requires a memcpy() of the entire contents of UBO #0. We
could create a synthetic UBO instead with sysvals at the end.
* We want to push uniforms/sysvals. Currently we push UBO #0 as much as
we can, which pushes sysvals automatically by point 1.
* We want to optimize out f2f16(uniform). We don't currently handle
this.
* We want to optimize out uniform-on-uniform/constant operations. Mesa
doesn't currently have good support for this.
The real solution will look something like:
* Create a separate UBO for sysvals.
* Let the compiler allocate push constant space as it sees fit ("copy
word 12:15 of UBO 1 to word 2:3 of push constant space, as fp16").
* Somehow handle uniform folding when NIR gains support.
For now, let's not block the depostfixening.

This is the easy subset, where we have functions that take in a postfix
pointer but only to use as a return address. We can use an actual return
instead, which is a bit simpler and helps prepare for condensed postfix

Mali has a special 5:3 encoding representing a subset of the natural
numbers, of the form:
a * (2^b)
for a odd and b natural/zero. It is used for padding out instance sizes,
as well as in attribute records so it's worth representing as a native
type as opposed to having manual packs/unpacks in various places.
