 Description   

A number of our internal api's, such as safenum, require fixed width integer types. I'd like to consider what adding user defined fixed width integer types might look like.

The idea being that one could:

42i64 == static_cast<int64_t>(42LL)

1234u32 == static_cast<uint32_t>(1234UL)

etc.

Mostly a quality of life issue

This is probably blocked on the upgrade to msvc 2015, as vc12 lacks support for user defined literals

Note that we may get this in the future anyway per http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p1280r0.html

Per discussion with mira.carey@mongodb.com, we are deciding against doing this.
