Add a map method to std::ops::range::Bound, patterned off of the method
of the same name on Option.

Have left off creating a tracking issue initially, but as soon as I get the go-ahead from a reviewer I'll make that right away 😄

@glittershark Can you give some motivating examples for adding this to the standard library? I can't think of many situations where this function would be used, and the doc example you included seems a bit contrived.

@m-ou-se at work we use Bounds to represent range lookups on compound indices (for a database), and we use (an extension trait providing) the map method to do things like turning bounds of vecs into bounds of tuples once we're in a place where the length is known statically, or to serialize the contents of a bound when doing lookups into lower-level storage layers (rocksdb, in our case). To give a sense of scale, that extension trait is imported 11 times in a >100KLoC codebase.
