// Implementation of all inlined member functions defined in oop.hpp

// Separate this out to break dependency.

// is_perm only verifies that oop is in the reserved space for
// the perm gen. Things like forte stackwalking need something that
// assures us that the pointer is in the commited area so we don't
// segv checking suspicious frame contents.
