NIR doesn't have atomic loads/stores, so we have to workaround that with
this for dEQP-VK.memory_model.* to pass.

d169f09e37 aco: be more careful combining additions that could wrap into loads/stores
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.

9a089baff1 aco: optimize boolean phis with uniform selections
Even though the boolean can be divergent, the control flow can be (at
least partially) uniform. For example, we don't have to create any
s_andn2_b64/s_and_b64/s_or_b64 instructions with this code:
a = ...
loop {
    b = bool_phi a, c
    if (uniform)
        break
    c = ...
}
d = phi c

The pass should now create much less linear phis.

ca51f75f9d aco: fix more validation errors from vgpr spill/restore code
It looks like the attempt to fix this in 1e791e51a6 was incomplete.

This fixes crashes with Devil May Cry 5 with a debug build.
