- Add AllocaFrame field to the exception registration record. It is required for Clang and C++ handlers.
- Fix the way how "nested functions" are emulated on Clang and C++, respecting the fact that the compiler can and will use a temporary esp-based stack frame below any alloca-allocations for function invocation. This uses the AllocaFrame field to calculate and setup a new temp stack frame for the "nested functions".
- Make use of the HandlerType field in the exception registration record to use different methods for invoking filters / finally functions.
- Write @_SEH3$_CallRtlUnwind@4 in raw asm instead of inline, because Clang cannot deal with stdcall decorations in inline asm (see http://llvm.org/bugs/show_bug.cgi?id=19027)
- Make sure ExceptionPointers are properly initialized in _SEH3$_except_handler
