Function `aggregate_raw_ptr`

const fn aggregate_raw_ptr<P: bounds::BuiltinDeref, D, M>(data: D, meta: M) -> P
where
    <P as bounds::BuiltinDeref>::Pointee: ptr::Pointee<Metadata = M>

Lowers in MIR to Rvalue::Aggregate with AggregateKind::RawPtr.

This is used to implement functions like slice::from_raw_parts_mut and ptr::from_raw_parts in a way compatible with the compiler being able to change the possible layouts of pointers.
