Add the start of a test suite that compares tvix eval results against
nix, using the string repr of the value as the comparison. This shells
out to a nix-instantiate binary, which is configurable as an environment
variable, to eval - there's some extra machinery there to setup a new
nix store as a tempdir to allow running this test inside the nix build
for tvix-eval itself.
Currently this has a macro that'll allow writing lots and lots of
hardcoded tests, but going forward I'm also going to be looking into
adding proptest-based generation of expressions to compare.

This trait can be used to convert most structures from rnix-parser
into a codemap::Span. It uses a macro to implement the trait for the
various expression types in the rnix AST, as Rust's silly semantic
versioning restriction stops us from doing a blanket implementation.
This will be used in the next commit to clean up the span handling in
the compiler a bit.

Yep.
This is kind of ugly right now. The idea is that the recursive_scope
compilation function is used for recursive sets as well by emitting
the keys. The rest of the logic is pretty much identical.
There is quite a lot of code here that can be cleaned up (duplication
between attrs and let, duplication inside of the recursive scope
compilation function etc.), but I'd like to get it working first and
then make it nice.
Note that nested keys are *not* supported yet.

This type is used in the list temporarily populated by the *second*
pass over all identifiers in a recursive scope. This first pass only
serves to make all bindings known to the compiler, without populating
their values yet.
Having a type here is going to be useful once we implement `rec`,
which needs to thread through slightly more information.

This makes the phases of attribute set construction that Nix has very
explicit (inherits, static keys, dynamic keys).
This change focuses on the split between dynamic/static keys by
collecting all dynamic ones while compiling the static ones, and then
phasing them in afterwards. It's possible we also need to do some
additional splitting inside of the inherits.

This function is necessary for all builtins that expect some form of
path as an argument. It is merely a wrapper around coerce_to_string that
can shortcut if we already have a path. The absolute path check is done
in the same way as in C++ Nix for compatibility, although it should
probably be revised in the long term (think about Windows, for example).
Since coercing to a path is not an operation possible in the language
directly, this function can live in the builtins module as the only
place it is required.

With this puzzle piece of string compilation in place, `compile_str`
becomes less redundant, as every part now needs to be compiled the same.
The thunking logic becomes a bit trickier, since we need to thunk even
in the case of `count == 1` if the single part is interpolating.
Splitting the inner (shared) code in a separate function turned out to
be easier for making rustc content.

If we have multiple string parts, we need to thunk assembling the
string. If we have a single literal, it is strict (like all literals),
but a single interpolation part may compile to a thunk, depending on how
the expression inside is compiled – we can avoid forcing to early here
compared to the previous behavior.
Note that this CL retains the bug that `"${x}"` is erroneously
translated to `x`, implying e.g. `"${12}" == 12`.
The use of `parts.len()` is unproblematic, since normalized_parts()
builds a `Vec` instead of returning an iterator.

Implement C++ Nix's `EvalState::coerceToString` minus some of the Path
/ store handling. This is currently only used for `toString` which does
all possible coercions, but we've already prepared the weaker coercion
variant which is e.g. used for builtins that expect string arguments.
`EvalState::coerceToPath` is still missing for builtins that need a
path, but it'll be easy to build on top of this.
