Dave Bort 45de8bf76e Add generic VMAddress-related types
This will allow sharing code that is currently hard-coded to use (e.g.)
LinuxVMAddress or mach_vm_size_t.

//!
//! This class checks bases of type #VMAddress and sizes of type #VMSize against
//! a process whose pointer type is either 32 or 64 bits wide.
//!
//! Aside from varying the overall range on the basis of a process pointer type
//! width, this class functions very similarly to CheckedRange.
