Deliberations on efficiency of std::vector on x64 Linux.
New allocator proposed and benchmarked.

mm :: allocPopulate

An allocator that can speed up operations by pre-populating memory pages with physical frames. Policies:

• mm::allocPopulate_base::popFull - physicall frames are assigned to whole allocted memory
• mm::allocPopulate_base::popHalf - lower half of memory have frames assigned
• mm::allocPopulate_base::popNone - no frames assigned, policy just for comprsion with others

mm :: allocPreserve (doesn't work)

An allocator that reuses deallocated memory. Prevents memory fragmentation with memory remapping.
