[Bug 20331] VirtualAlloc() should allocate addresses low to high

What is considered low addresses depend on the preloader allocations. You can
play with the WINEPRELOADRESERVE variable if you want to change that range.

The rest of the memory is under control of the kernel, that's required for Unix
libraries to be able to allocate memory. I don't quite understand why you have
to depend on the order of allocation to determine the available memory (and of
course that may break on Windows too, cf. the registry key you mentioned).
