This means that our binary does not need to include concatenated strings such
as "set CanvasRenderingContext2D.fillStyle". It only needs to contain the
individual strings "CanvasRenderingContext2D" and "fillStyle" which are most
likely already present in the binary.
This change reduces the binary size on macOS x64 by around 200KB.
Here's a diff of the impact on the code generated for Attr_Binding::get_specified
in the Mac build. This change makes us generate slightly more code, which is
very much offset by the reduction in the amount of strings we ship.
