SIL.rst: "dealloc_ref" shouldn't clean up values.
After discussion with John, we decided that we need to be able to deallocate a partially-initialized box during initializer execution, in case an initializer expression ends up unwinding before a value is fully initialized. When optimizing reference type allocations, it would also better to expose the destructor call and release operations directly instead of hiding them inside an instruction.
