[v4 1/2] mscoree: Make vtable and tokens local declarations arch independent.

My preference would be for the types to always match the flag checked.
If we're using a pointer type then we should also decide on a flag by
checking for _WIN64. But it's not really important since we have to
add support for each architecture individually.
