For name/value pairs (which occur extremely often in Nix and make up a
significant chunk of the runtime cost of evaluating nixpkgs) we
substitute an optimised representation.
For now this will only be used if the name/value pair keys were
specified as literal identifiers or strings (i.e. if chunks are
encountered as keys they are not forced and a normal attribute set
backed by a map will be constructed).

Users may construct a pair that falls into the name/value optimisation
but where `name` is not actually a string, as from the language
perspective there is nothing special about this attribute set.
We also can not conditionally apply this by forcing the key at this
point, as this would change the language semantics.
Therefore, the name in the optimised representation is also carried as
`Value`.

This adds a new instruction which assembles an interpolated string
from a specified number of fragments, which are already going to be
located on the stack in the right position.
This will raise a type error if any of the fragments do not evaluate
to a string.

This sets up the scaffolding for compiling interpolation, but those
instructions do not yet exist.
