This is not a compelling change in isolation, but it is a necessary step.
It's unused.
It has a single use, which is easily changed to something better.
And remove the `unsafe` blocks, they're not necessary.
Also rewrite `InternedString::{with,with2}` to use the new functions.
Finally, add some comments about the speed of the
`as_str()`/`as_interned_str()` functions.

…tring, r=petrochenkov Minimize uses of `LocalInternedString` `LocalInternedString` is described as "An alternative to `Symbol` and `InternedString`, useful when the chars within the symbol need to be accessed. It is best used for temporary values." This PR makes the code match that comment, by removing all non-local uses of `LocalInternedString`. This allows the removal of a number of operations on `LocalInternedString` and a couple of uses of `unsafe`.
