<pre>We're losing, what is presumably, our depth write:
pass -> fail
mov(8) g123<1>F g2<0,1,0>F
mov(8) g124<1>F g2.1<0,1,0>F
mov(8) g125<1>F g2.2<0,1,0>F
mov(8) g126<1>F g2.3<0,1,0>F
-mov(8) g127<1>F g2.1<0,1,0>F
sendc(8) null g123<8,8,1>F
render RT write SIMD8 LastRT Surface = 0 mlen 5 rlen 0
The mlen is still correct, so we're writing uninitialized values.
Checking out commit 1ca60de4c (before we deleted the non-NIR paths), you can
run with INTEL_USE_NIR=0 and the test passes.</pre>
