[WinEH] Adjust the 32-bit SEH prologue to better match reality

It turns out that _except_handler3 and _except_handler4 really use the
same stack allocation layout, at least today. They just make different
choices about encoding the LSDA.

This is in preparation for lowering the llvm.eh.exceptioninfo().
