a060c8f467 refactor(tvix/eval): use call frame for top-level lambda
This wires up most of the machinery for executing different call
frames inside of the VM and stuffs the top-level lambda which the
compiler outputs in there, as well.

6f31c895ff refactor(tvix/eval): return a lambda from the compiler
Changes the internal compiler plumbing to not just return a chunk of
code, but the same chunk wrapped inside of a lambda value.

This is one more step towards compiling runtime lambdas.

f7305eed47 refactor(tvix/eval): collect vector of errors in compiler
Instead of exiting the compiler at the first sight of an error,
skip any erroneous nodes and continue compiling, collecting more
errors along the way.

This paves the way for nicer error reporting in which multiple errors
can be reported at once, avoiding situations in which users are
hunting a fault error-by-error and possibly getting distracted by
less useful output.

This starts paving the way for nicer, source-code based error
reporting.

Right now the code paths in the VM do not emit annotated errors, as we
do not yet preserve that structure from the compiler. However, error
emitting code paths in the compiler have been amended to include known
nodes.

813fb98470 refactor(tvix/eval): Upgrade to latest rnix-parser
Since the latest published version of rnix-parser on crates.io, the
crate has undergone major changes which are only available in the git
repository at the moment. This commit updates the compiler to this
newer version of rnix.

Most notably, the entire AST provided by rnix is now wrapped in the
AST type system. As a result of this traversal is much nicer in many
places, especially for things like nested attribute selection.

There are a handful of smaller features missing for full feature
parity with the previous version, especially handling of path
literals, but PRs for these already exist in rnix-parser.

8fa3bc7137 feat(buildkite/mkPipeline): allow fast failure for build steps
This is supposed to help with resource wasting in situations when
multiple dynamic steps depend on a failing derivation. Cost of
failure currently is `C = T * D` where:
 - T -> time to compile the failing derivation
 - D -> amount of CI targets depending on a failing derivation

Switching to `Fail Fast` limits it to just T (time of a single
failure). Which helps a lot, especially while upgrading nixpkgs.

Fast fail at this moment is in preview, so to enable it:
 - Enable `Fail Fast` feature at pipeline or organization level
 - Set `cancelOnBuildFailing` parameter to true for `mkPipeline`

0f739cd944 feat(tvix/eval): implement scope poisoning for true/false/null
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.

0b51d63081 refactor(tvix/eval): simplify let ... in ... before recursion
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.

7cfdedfdfb feat(tvix/eval): compile with expression
Adds an additional structure to the compiler's scope to track the
runtime "with stack", i.e. the stack of values through which
identifiers should be dynamically resolved within a with-scope.

When encountering a `with` expression, the value from which the
bindings should be resolved is pushed onto the stack and tracked by
the compiler in the "with stack", as well as with a "phantom value"
which indicates that the stack contains an additional slot which is
not available to users via identifiers.

Runtime handling of this is not yet implemented.

This however breaks valid code, such as:

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.

de26894814 refactor(tvix/eval): remove Error::InvalidKeyType
We're confident that we're handling all branches that can reasonably
occur from valid AST, any other cases should be considered a critical
evaluator bug and panic rather than surfacing something that looks
like user error.

2ea71aa4c3 fix(tvix/eval): null in dynamic attribute keys skips the element
This is actually *tested* behaviour in C++ Nix, so we need to
implement it here, too.

e041851581 feat(tvix/eval): implement chunk disassembler output
This makes for a much nicer view of an execution if `--feature
disassembler` is set, for example:

  === compiled bytecode (11 operations) ===
  02   OpConstant(1)
  02   OpConstant(2)
  02   OpConstant("a")
  02   OpConstant(1)
  02   OpAttrs(1)
  02   OpList(3)
  02   OpGetLocal(0)
  02   OpConstant(1)
  02   OpList(1)
  02   OpConcat
  02   OpCloseScope(1)
  === runtime trace ===
  0001 OpConstant(ConstantIdx(0))  [ 1 ]
  0002 OpConstant(ConstantIdx(1))  [ 1 2 ]
  0003 OpConstant(ConstantIdx(2))  [ 1 2 "a" ]
  0004 OpConstant(ConstantIdx(3))  [ 1 2 "a" 1 ]
  0005 OpAttrs(1)                  [ 1 2 { a = 1; } ]

  0007 OpGetLocal(0)               [ [ 1 2 { a = 1; } ] [ 1 2 { a = 1; } ] ]
  0008 OpConstant(ConstantIdx(4))  [ [ 1 2 { a = 1; } ] [ 1 2 { a = 1; } ] 1 ]

57d0dbb1c6 feat(tvix/eval): implement optional runtime tracing
This adds a `disassembler` feature to the crate configuration that
traces the operations executed and the state of the stack at runtime.

This can be enabled by compiling with `--feature disassembler`.

This will also gain a more sensible layout of code slices eventually.
