When the LD_VAR is only used once as an input to a texture instruction,
this is an improvement. We handle this case as a backwards pass.

Set the .skip bit on texture instructions and the terminate discarded
threads bit on the clause header based on data flow analysis of helper
invocations. This code is adapted from Midgard, which requires the same
analysis with a few details changed.

Redundant with the texture operation descriptor, but we don't want to
parse that in the rest of the compiler. Handling it as a pseudo-modifier
lets us share a code path with TEXS.

This reduces number of spills and hence compile-time by avoiding
pointless decisions. In a terrain shader forced to use full threads:
Before: 39:168 spills:fills
After: 23:127 spills:fills

Bifrost v7 trades off register pressure and occupancy. If we restrict to
[R0, R15] U [R48, R63], we get full occupancy, but if we use the full
register file, we only get half occupancy. Try to allocate just 32
registers, and only use the full 64 registers if that would spill.
Clever heuristics could make this both more effective (live range
splitting, shuffling, spilling if deemed acceptable) and cheaper at
compile-time (tracking maximum liveness to determine if it's possible to
hit at all). For now, this should suffice.

Android.mk files haven't really been supported by Mesa devs for a long
time. Most of us have been willing to update Makefile.sources if we
remember and sometimes we try to blind code some Android.mk for a new
generator. However, the reality is that it breaks regularly and ends up
being maintained by the Android community. To address this problem
another approach was implemented in !10183 utilizing the maintained
meson build system. The old Android.mk files are no longer required.
This commit was created with the following commands:
git rm **/Android.mk
git rm **/Android.*.mk
git rm **/Makefile.sources
git rm CleanSpec.mk

Bifrost has a new type of job called 'index-driven vertex', which takes
in two shaders. The primary shader, called for all values, performs
position shading to a cacheline-aligned attribute buffer. The secondary
shader, called for values still live after culling, performs varying
shading.
It is the responsiblilty of the implementation to ensure that vertices
from different instances do not share a cacheline.

The Gallium and Vulkan drivers will soon use different memory pool
implementation, but some pieces in libpanfrost depend on pan_pool. Let's
split the implementation so we have common bits still available while
letting the drivers implement what really matters: the allocation logic.
All the generic pieces are prefixed pan_pool, and what will become the
gallium implementation is prefixed panfrost_pool. We'll then duplicate
the panfrost_pool bits in panvk and prefix it with panvk_pool, and
implementations will start diverging from there.

Pass a memory pool to pan_blit_ctx_init() instead of creating a new pool.
Useful for Vulkan since the descriptor pool is at the command buffer
level and is thus shared by all blit batches. Doing this will save us a
BO ownership transfer.

Read directly from the instruction getting spilt. Otherwise a fill
will be inserted before the spill writing the value, so the
instruction reading the spilt value gets garbage data.
Use the bundle_id to check if the instructions are in the same bundle.
Insert a move instruction, as the spill needs the value in a LD/ST
register such as AL0, while the ALU instruction reading the value
needs it in a work register such as R0.
