Rather than recompute liveness every block, compute it just once for the
whole shader, which ends up more efficient.

Rather than O(N) each call, we can precompute the whole set - also O(N)
- and then subsequent checks are O(1).

The test and rewrite were both accidentally O(N) to the shader size when
they should be O(1), so overall this takes the pass from O(N^2) to O(N).

With this, we may remove all invert passes and simply look at the src
modifier on NIR->MIR and fixup at pack time. No shader-db changes.

We have to restructure to ensure NIR->MIR does not mutate the NIR and to
allow passing around dest/outmods for the new helpers. If NIR->MIR were
better designed this would be easier. Sigh.

With the goal of removing modifiers from NIR, these helpers let us
detect modifier patterns without mutating the underlying NIR. These were
intended for upstream, but due to various issues are being (temporarily)
vendored.

We don't actually support Z32_UNORM; the format we've been using as such
is in fact Z24X8 / Z24S8. Fix that and drop Z32_UNORM.

Rather than heuristically guessing what PIPE formats correspond to what
in the hardware, hardcode a table. This is more verbose, but a lot more
obvious -- the previous format support code was a source of endless
silent bugs.
v2: Don't report RGB233 (icecream95). Allow RGB5 for texturing
(icecream95).

We create a hash table mapping GPU va's to mmap structures, such that
searching for a mapped address is effectively O(1) rather than O(N) to
the number of mapped entries as with the previous linked list approach.
This is a memory-time tradeoff, but the speed-up is tracing is notable.

Corresponds roughly to what we analyze. Note that "terminate AND
execute" is a contradiction (rather: it's equivalent to just
terminating), hence why there are only three possibilities for the
states of the flags:
.cont = continue, don't execute
.last = don't continue, don't execute
.cont.last = continue and execute

This fixes the sky being red in OpenMW, as well as some of the Mesa
demos using shadows (shadowtex, shadow_sampler).

src/panfrost/shared is shared with lima driver, build
bifrost_compiler for lima driver is meaningless and
get link error when only lima driver is enabled.
So only build bifrost_compiler when configued with:
meson -Dtools=panfrost
