[4/7] vcomp: Implement _vcomp_for_static_simple_init and _vcomp_for_static_end.

[Sebastian Lackner]

In this and the following patches the function signatures (especially the differences
between signed <-> unsigned variables) are guessed based on the tests, so that type
conversions are not necessary.

If someone is aware of any (wine compatible) better way to find out the real types
(documentation / public header files / ...), feel free to tell me. ;)
