[PATCH 0/3] MR8067: Fixes for compiler __try/__except support

[Jacek Caban (＠jacek)]

This change allows building with compiler exception support enabled (`-DUSE_COMPILER_EXCEPTIONS`) on non-i386 targets.

On i386, `_except_handler3` needs to be available. While we provide it as an import from the msvcrt DLLs, that's not sufficient for modules like
kernel32. Making this work would likely require moving `_except_handler3` to `winecrt0`.

In practice, this fixes the build with Clang, although the resulting binaries do not appear to be fully correct yet. Further investigation is needed, likely on the LLVM side.
