0b5bb3b2b4 Fix 3 MSVC warnings: 
'void (__cdecl *)()' differs in parameter lists from 'void (__cdecl *)(void)'

atexit really expects a "void f(void)" function.

d9e57c146d Fix MSVC warning: "is out of range for enum constant" 
MSVC doesn't support 64 bit enum. 
OpcodeMask is not used anywhere in the code base.

52f6a4de95 Fix some issues Duncan found in the previous commit. 
I kept the reference to the ABI since that is the common case. The
-fno-asynchronous-unwind-tables option is a user controlled way of breaking
the ABI.

6cd71c6292 Fix warning in the CMake build about redefining LLVM_PATH_XDOT_PY by making sure both definitions are identical. This used to produce warnings like

(Paths edited for clarity)

Note: This only affected people who had xdot.py installed.
