Expand description

Intern an allocation. Returns Err if the allocation does not exist in the local memory.

mutability can be used to force immutable interning: if it is Mutability::Not, the allocation is interned immutably; if it is Mutability::Mut, then the allocation must be already mutable (as a sanity check).

Returns an iterator over all relocations referred to by this allocation.
