libproc_macro: Manual Clone for Literal
The Literal type may contain foreign byte array when representing a byte
array or a string. This means auto deriving the Clone trait would only
perform a shallow copy of the pointer rather than a deep copy. This
behavior would lead to use-after-free when a literal is cloned and then
dropped.
ChangeLog:
* librust/proc_macro/rust/bridge/literal.rs: Implement Clone
manually.
