Defines the virtual file system interface vfs::FileSystem.
A smart pointer to a reference-counted object that inherits from RefCountedBase or ThreadSafeRefCount...
This is an optimization pass for GlobalISel generic memory operations.

OutputIt move(R &&Range, OutputIt Out)
Provide wrappers to std::move which take ranges instead of having to pass begin/end explicitly.
Definition: STLExtras.h:1849
Implement std::hash so that hash_code can be used in STL containers.
