We theoretically could push these sizes to the const file
opportunistically, which appears to be what the blob does, but the
maximum number of SSBO's is way too big to do that unconditionally. Just
use resinfo to get the size for now.

This change mostly touches error handling code paths, where a
bug was found when the DRI driver failed to bind a new DRI
context. Specifically, the reason for it to fail was the window
system unable (for whatever reason) to provide the DRI drawable
with a buffer. In this instance, Mesa un-does the EGL bindings,
but doesn't restore the old DRI context, hence remaining in a
funny state. It's worth mentioning that despite trying, there
is no guarantee that the old DRI context can be restored,
depending on the runtime.
Before this change, if bindContext() failed then
dri2_make_current() would rebind the old EGL context and
surfaces and return EGL_BAD_MATCH. However, it wouldn't rebind
the DRI context and surfaces, thus leaving it in an
inconsistent and unrecoverable state.
After this change, dri2_make_current() tries to bind the old
DRI context and surfaces when bindContext() failed. If unable
to do so, it leaves EGL and the DRI driver in a consistent
state, it reports an error and returns EGL_BAD_MATCH.

This adds a nir_unsigned_upper_bound() helper which does something similar
to nir_analyze_range() except it tries to obtain the largest possible
value instead of it's relation to zero.
It also adds nir_addition_might_overflow(), which uses this helper to try
to prove that an unsigned addition does not wrap around.

This (combined with a pass to actually set the corresponding NIR flags)
should help fix a lot of the regressions from the SMEM addition combining
change.

SMEM does the addition with 64-bits, not 32. So if the original code
relied on wrapping around (for example, for subtraction), it would break.
Apparently swizzled MUBUF accesses also have issues with combining
additions that could overflow. Normal MUBUF accesses seem fine.

This should be much better than the previous method that was more
guesswork-based than anything else. It returns a value within 1 of the
blob for every input value I've tested, and it seems like it returns
slightly better (but still legal) answers when it differs.

For implementing panfrost_flush, it suffices to wait on only a single
syncobj, not an entire array of them. This lets us wait on it directly,
without coercing to/from syncfds in the middle (although some complexity
may be added later to support Android winsys).
Further, we should let the fence own the syncobj, tying together the
lifetimes and thus removing the connection between syncobjs and
batch_fence.

With the current kernel UABI, there is no benefit to explicitly
specifiying dependencies, since the kernel by design adds implicit
dependencies to any referenced BOs. This is something we'd like to
address in the future, but efficient handling with future kernels will
require a tweaked design in userspace as well. So let's do the obvious
thing now, and extend later.

We don't want these files shared between builds (it'll get blown away by
the next rsync), and NFS will just increase our latency for hitting the
cache.
Drops a630 gles31 run from 11-17 minutes to 5.5. Maximum cache size on a
run I've seen is 153M, which it seems we can easily spare.

The intention here was to check "Would the GPU be able to compress
this if we used the PBO-based texture upload path?" Prior to Gen12,
that meant checking for CCS_E. On Gen12, there are a lot more types
of compression, and basic CCS_E was replaced by GEN12_CCS_E, making
this check simply not work, so we'd take the CPU path instead.
Instead, check if it has CCS, and isn't the basic "fast clear" CCS_D.
