09ea05cf23 rusticl: skip bindgen for pipe_shader_state_from_tgsi
bindgen up to at least 0.72.1 generates invalid code (see below) and
that function is not used, so simply skip it.

addc719ec2 radv: workaround has_smem_partial_oob_access_bug
Just use an existing flag to increase the bo size slightly.

Fixes a ring gfx timeout with
dEQP-VK.spirv_assembly.instruction.compute.opfma.fp32.vec3.undef.denorm_flush.directed

7c6be36cf4 aco: don't emit waitcnts before subgroup-scope execution barriers

InvThroughput: 19424631 -> 19754358 (+1.70%); split: -0.00%, +1.70%

I don't think the stats are very accurate. This seems to often move the
s_waitcnt down into a divergent branch, but the wait still happens later
if the branch isn't taken, so the wait is counted twice.

e8ab81cc3a brw: fix null render target decision
First, use 64bit values everywhere since shader_info::outputs_written
is a 64bit field.

Second, alpha to coverage should only be considered for draw buffer 0
as stated in the GL spec (quoting Version 4.6 (Core Profile), 17.3.1
Alpha To Coverage) :

   "All alpha values in this section refer only to the alpha component
    of the fragment shader output linked to color number zero, index
    zero (see section 15.2.3)."

Third, the write message setup in brw_compile_fs.cpp was not taking
into account alpha-to-coverage being disabled anymore.

1a9a0a15f7 ir3: lower undef booleans to zero
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
macOS-CI / macOS-CI (xlib) (push) Waiting to run
We are generally fine with undefs. However, booleans are only allowed to
contain 0/1 but are stored in 16b registers. Undefs may cause such
registers to be uninitialized and contain values other than 0/1. This
especially happens with undef booleans in phi srcs, which are explicitly
left uninitialized. In general, such non-0/1 values don't cause problems
because we mostly use booleans by comparing them to 0. However, they do
cause problems in special cases like `inot(x)` which we lower to `sub(1,
x)` which only works if true==1.

Fixes misrenderings in "Kingdoms of Amalur: Reckoning".
