2022-08-14 r/4443 refactor(tvix/rm): introduce helper for AttrSet Entry APIVincent Ambo1-20/+27
There are multiple points where an insertion needs to be done into an attribute set, but copying the key or checking for presence before insertion should be avoided As that is a little bit noisy, it's been factored out into a helper function in this commit.

2022-08-14 r/4442 feat(tvix/vm): implement first nested attribute set constructionVincent Ambo2-39/+134
This can construct non-overlapping nested attribute sets (i.e. `{ a.b = 1; b.c = 2; }`, but not `{ a.b = 1; a.c = 2; }`). In order to do the latter, it's necessary to gain the ability to manipulate the in-progress attribute set construction. There's multiple different options for this ...

2022-08-13 r/4439 feat(tvix/eval): construct internal attribute path representationVincent Ambo4-1/+30
This is required for constructing nested attribute sets at runtime. There'll be quite a lot of optimisation potential with this solution eventually, if it should turn out to be a bottleneck. This introduces a conceptual change, in that the `Value` enum is now an enum representing "all runtime values" instead of "all Nix language types". This makes sense in general, as this type will also contain Chunk representations etc. which are not exposed to users.

2022-08-13 r/4438 feat(tvix/vm): implement construction of optimised KV attrsetsVincent Ambo1-0/+77
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).

2022-08-13 r/4437 fix(tvix/value): KV struct needs to carry name as Value, tooVincent Ambo1-1/+2
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`.

2022-08-13 r/4427 feat(tvix/eval): implement trivial attribute set literalsVincent Ambo3-3/+88
Implements attribute set literals without nesting. Technically this already supports dynamic key fragments (evaluating to strings), though the only way to create these (interpolation) is not yet implemented. However, creating simple attribute sets like `{ }`, or `{ a = 15; }` or `{ a = 10 * 2; }` works. Recursive attribute sets are not yet implemented as we do not have any kind of scope access yet anyways. This is implemented using a new instruction that creates an attribute set with a given number of elements by popping key/value pairs off the stack.
