test_instanced_draw() fails systematically on cw-rx460:

https://test.winehq.org/data/patterns.html#d3d10core:d3d10core

d3d10core.c:9275: Test failed: Got 0xfff0f010, expected 0xff80f010 at (160, 0), sub-resource 0.
d3d10core.c:9275: Test failed: Got 0xfff0f040, expected 0xff80f040 at (240, 0), sub-resource 0.
d3d10core.c:9275: Test failed: Got 0xffaaaacc, expected 0xffbbaacc at (480, 0), sub-resource 0.
d3d10core.c:9275: Test failed: Got 0xffaaaa90, expected 0xffbbaa90 at (560, 0), sub-resource 0.

It turns out that this happens when running test_il_append_aligned() and 
test_instanced_draw() in parallel. So would it be acceptable to run 
test_instanced_draw() after the other tests as in the patch below or 
should this be investigated some more?

That seems fine as a solution. It may still be interesting to figure
out whether test_il_append_aligned() or test_instanced_draw() is to
blame here though. (E.g., if you queue multiple instances of either
test_il_append_aligned() or test_instanced_draw() does that also
introduce failures? Is there any particular part of
test_il_append_aligned() that introduces failures in
test_instanced_draw()?)
