Placement operator new: returns the supplied pointer unchanged without allocating, so an object can be constructed at a caller-provided address. Declared in these headers only as a forward declaration for use when the <new> header is unavailable in the kernel environment; the freestanding C++ ABI supplies the trivial definition.
