Title: Mark some things as nothrow

This just marks a select few methods in `rt.lifetime` as nothrow, since they can't throw. Two were also marked as pure, and one as @safe, when applicable.

That's it.

I need these changes for a later non-trivial change, and I preferred getting this in independently first.
