merge vm_version_x86_{32,64}.hpp

[Vladimir Kozlov]

Actually we are merging x86 source as much as possible
to avoid duplicated changes for 32- and 64-bits.
Steve Goldman started this work and Tom did additional changes.
So Christian's suggestion is in the line with this work.

It is better to have 2 files with few #ifdef then 4 separate file
which have 80% (or more) of the same duplicated code.

Thanks,
Vladimir
