Signed-off-by: Paul Gofman pgofman@codeweavers.com --- In particular, fixes a semi-random crash in ntdll exception test (test_extended_context) I am now reproducing locally. The thread is created suspended while the main thread sets context to it. (to_flags & CONTEXT_AMD64_XSTATE) is always TRUE.

Hi,
While running your changed tests, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?
Full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=102650
