2022-08-31	r/4561 feat(tvix/eval): implement scope poisoning for true/false/null	Vincent Ambo	4	-0/+15
	These tokens are optionally parsed as identifiers by Nix, which means that within any scopes that resolve them the compiler needs to track whether they have been overridden to know whether to emit the literal instructions or resolve a variable. This is implemented by a new concept of "scope poisoning", where the compiler's scope structure tracks whether or not any builtin identifiers have been overridden.

2022-08-31	r/4560 refactor(tvix/eval): simplify `let ... in ...` before recursion	Vincent Ambo	2	-0/+8
	While full recursion through thunking is not available, there are actually incorrect behaviours introduced by declaring before binding (example in the newly introduced test). This commit simplifies the implementation to avoid this issue, and also because I intend to explore a bit more how far we can get in non left-to-right bindings without introducing thunks immediately.

2022-08-31	r/4549 feat(tvix/eval): implement inherit in let expressions	Vincent Ambo	2	-0/+9
	Note that at this point recursive bindings do not yet work in either attrsets or let, so inheriting from the same scope is generally not possible yet.

2022-08-31	r/4548 feat(tvix/eval): implement `inherit` in attribute set literals	Vincent Ambo	4	-0/+6
	Straightforward implementation, evaluating the elements of an inherit and preparing the stack so that `OpAttrs` sees all relevant values when constructing the attribute set itself. The emitted instructions for inheriting a lot of values from the same attribute set are inefficient, but it's too early to say whether this actually matters.

2022-08-30	r/4544 fix(tvix/eval): `?` operator should use OpAttrsOrNotFound	Vincent Ambo	2	-0/+4
	Using `OpAttrSelect`, the ? operator will fail when encountering a nested value that is not an attribute set. This however breaks valid code, such as: { bs = 42; } ? bs.a.b The fix is simply to use the same operator used in the `or` statement, which leaves a sentinal on the stack if a field is not found or the value is not an attribute set.

2022-08-30	r/4543 fix(tvix/eval): `or` should handle non-attrset values, too	Vincent Ambo	2	-0/+3
	If a nested attrpath encounters a non-set value, the sentinel value denoting a lack of next values should be emitted. This mirrors the behaviour of Nix.

2022-08-25	r/4478 feat(tvix/eval): implement binary comparison operators	Vincent Ambo	16	-0/+72
	This is accomplished by simply delegating to the Rust implementations of (Partial)Ord and (Partial)Eq, which are implemented for Value and underlying wrapper types to behave like they do in Nix. To ease the implementation overhead, a new comparison operator macro has been added to the VM module. Incomparable types will raise a new error variant when a comparison is attempted, containing both supplied types. This mimics the information carried in the error thrown by C++ Nix.

	The underlying implementation does a few tricks based on which pair of attrset representations is encountered. Particularly the effect of short-circuiting the empty cases might be relevant in nixpkgs/NixOS, due to the use of lib.optionalAttrs.
