This reverts commit r236360. This change exposed a bug in WinEHPrepare by opting win32 code into EH preparation. We already knew that WinEHPrepare has bugs, and is the status quo for x64, so I don't think that's a reason to hold off on this change. I disabled exceptions in the sanitizer tests in r236505 and an earlier revision. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236508 91177308-0d34-0410-b5e6-96231b3b80d8
