Nekotekina ab248e170c vm_native.cpp: add MADV_HUGEPAGE 
It enables Transparend Huge Pages for some regions on Linux.
Although it can't be actively useful, it seems to do something.
Maybe it's even harmful for recompilers.

Nekotekina d1ee7c651f Make memory locking optional (mlock, VirtualLock). 
Fix desired locking operation (to fix "sudo" memory).
It was discovered that some systems have outdated configuration.
With too tight limit, it's almost impossible to lock anything in memory.

Nekotekina dcbe8ef5f4 Import VirtualAlloc2 if available (Win10+) 
Import MapViewOfFile3 as well.
Unused, this crap is tricky.
