RFC: ERROR_SXS_CANT_GEN_ACTCTX trying to run atl80:atl

[Francois Gouget]

Both WineTest and the TestBot fail to run the atl80 tests because 
CreateProcess() fails with ERROR_SXS_CANT_GEN_ACTCTX:

https://test.winehq.org/data/41df83c50e1c3cfdd6e8ffb65de7838f8503632c/win10_...
-> see this line: atl80	load error 14001

On the TestBot a few configurations succeed:
https://testbot.winehq.org/JobDetails.pl?Key=87365
* 32-bit wvistau64, w8
* 64-bit wvistau64

Before the e618fb526d06 commit, WineTest was not even trying so the 
current situation is be somewhat better:

https://test.winehq.org/data/tests/atl80:atl.html

But does anyone know how to get the atl80 tests to run?
