RUSTSEC-2020-0107: hashconsing: hashconsing's HConsed lacks Send/Sync bound for its Send/Sync trait.

Description

Affected versions of hashconsing implements Send/Sync for its HConsed type without restricting it to Sendable types and Syncable types.

This allows non-Sync types such as Cell to be shared across threads leading to undefined behavior and memory corruption in concurrent programs.
