New weak package

The new weak package provides weak pointers.

Weak pointers are a low-level primitive provided to enable the creation of memory-efficient structures, such as weak maps for associating values, canonicalization maps for anything not covered by package unique, and various kinds of caches. For supporting these use-cases, this release also provides runtime.AddCleanup and maphash.Comparable.
