Windows allocates heap in low address space

@Phyx made a great observation on IRC: on Windows the MBlock allocator currently allocates MBlocks in low memory. This makes life significantly harder for the linker. VirtualAlloc has a flag, MAP_TOP_DOWN, to address this use-case. Fixing this should significantly improve the reliability of linking on Windows.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
