30de72fefb chore(tvix/eval): do not inherit scope depth in new scopes
This is no longer required, resolution is now more sane. Pointed out
by sterni in cl/6422.

0f59fe6601 feat(tvix/eval): implement initial fancy formatting for errors
This very closely follows the way it's done for warnings, but errors
have a lot more information available in some cases which we do not
surface yet.

Note also that due to requiring the `CodeMap`, this is not yet called
from eval.rs as the way that is threaded through needs to be
refactored, so only the method for reporting these errors as strings
is implemented so far.

Next steps for this will be to add a generic diagnostics module that
reduces some of the boilerplate for this between warnings & errors,
and which will also give us a good point in the future to switch to a
fancier diagnostics crate.

The majority of people in our community probably block ads anyways,
but might as well ...

The ad account is linked to the TVL legal entity.

The ad is configured not to use any personalised data. In testing it's
showing me lamps and shoes. This is the same kind of ad as on my

118ac68800 feat(corp/tvixbolt): use fancy warning formatting
Unfortunately the codemap-diagnostic crate doesn't provide a way to
get colour control characters written to an arbitrary writer, so this
is black & white only, but we can look at this later if we introduce
something even fancier. For now it's reasonable.

4f67cf221a feat(tvix/eval): implement initial fancy display for warnings
This implements an initial fancy display for warnings emitted by the
tvix compiler, using the codemap_diagnostic crate.

Each warning variant has an associated message, and optionally an
associated annotation for the span displayed to the user.

In theory we could get a lot more fancy with the display for specific
variants if needed (e.g. re-parse the AST and actually add multiple
semantic spans based on context), but this is already a good start.

Example:

  tvix-repl> let toString = https://tvl.fyi; in let inherit toString; in ({}: 42) rec {}
  warning[W004]: declared variable 'toString' shadows a built-in global!
   --> [tvix-repl]:1:5
    |
  1 | let toString = https://tvl.fyi; in let inherit toString; in ({}: 42) rec {}
    |     ^^^^^^^^ variable declared here

  warning[W001]: URL literal syntax is deprecated, use a quoted string instead
   --> [tvix-repl]:1:16
    |
  1 | let toString = https://tvl.fyi; in let inherit toString; in ({}: 42) rec {}
    |                ^^^^^^^^^^^^^^^

  warning[W002]: inherited variable already exists with the same value
   --> [tvix-repl]:1:40
    |
  1 | let toString = https://tvl.fyi; in let inherit toString; in ({}: 42) rec {}
    |                                        ^^^^^^^^^^^^^^^^^

  warning[W999]: feature not yet implemented in tvix: recursive attribute sets
   --> [tvix-repl]:1:70
    |
  1 | let toString = https://tvl.fyi; in let inherit toString; in ({}: 42) rec {}
    |                                                                      ^^^^^^

  warning[W999]: feature not yet implemented in tvix: closed formals
   --> [tvix-repl]:1:62
    |
  1 | let toString = https://tvl.fyi; in let inherit toString; in ({}: 42) rec {}
    |                                                              ^^

  warning[W003]: variable 'toString' is declared, but never used:
   --> [tvix-repl]:1:5
    |
  1 | let toString = https://tvl.fyi; in let inherit toString; in ({}: 42) rec {}
    |     ^^^^^^^^ variable declared here

  => 42 :: int

These are coloured when output to a terminal.

dea6d9b73b chore(tvix/eval): add dependency on codemap-diagnostic
This is a crate for source-span based error reporting. Since all of
our spans are already codemap spans, it is a good starting point.

We have to figure out quite a bit of logic for neat error printing;
later on if we want fancier presentation we might want to look at one
of the other libraries in this space like miette.

a0acbfa470 refactor(tvix/eval): refactor methods for parsing static idents
Refactors the methods used for determining whether an identifier in a
binding (i.e. an `rnix::Attr` node) is a static string, and extracting
it.

Previously all uses of this logic were for `let`-expressions, where
dynamic attributes are always an error. However, we need the same
logic to properly implement the phase separation of attribute set
compilation.

To facilitate this, the actual core logic of these methods now return
`Option`, and are only converted to errors in cases where the errors
are actually required.

7046604cfe fix(tvix/eval): place plain inherits in correct stack slots
We need to make sure that we compile all plain inherits in a let
expression before declaring any other locals. Plain inherits are special
in the sense that they can never be recursive, instead resolving to a
higher scope. Thus we need to compile their value, before declaring
them. If we don't do that, before any other local can be declared,
we cause a situation where the plain inherits' values are placed into
other locals' stack slots.

Note that we can't integrate the plain inherit compilation into the
regular 2-3 phase model where we defer the compilation of the value or
we'd compile `let inherit x; in …` as `let x = x; in …`.

4d8f35353b fix(tvix/eval): declare let inherit (from) locals before compiling
The recent change that split declaration of let based locals and the
compilation of their values did not touch locals bound by inherit in
let. These were previously declared and compiled immediately before
starting to work on the other locals introduced in a let.

In the case of plain inherits, this behavior is kept in this change,
because there's nothing wrong with it: The value of a plain inherit will
always resolve to a higher scope, either statically or dynamically.

Since inherit (from) expression might refer to other locals bound in the
same let, we need to handle them in the same three steps as ordinary let
based locals:

1. We need to declare the (uninitialised) locals.

2. We need to compile the expression that obtains their value. For this,
   we create a new thunk, since the from expression may very well return
   a thunk which we need to force before selecting the value we are
   interested in.

3. Thunks need to be finalised.

For 1., we create an extra pass over the inherits that already declares
and initialises plain inherits and notes inherit (from) expressions in
the entries vector after declaring them. 2. only needs a bit of adapting
to create the thunks for selecting if appropriate, the rest of the
existing code can be reused.

07ea30370e refactor(tvix/eval): capture entire with_stack in upvalues
This completely rewrites the handling of "dynamic upvalues" to,
instead of resolving them at thunk/closure instantiation time (which
forces some values too early), capture the entire with stack of parent
contexts if it exists.

There are a couple of things in here that could be written more
efficiently, but I'm first working through this to get to a bug
related to with + recursion and the code complexity of some of the
optimisations is distracting.

d75b207a63 refactor(tvix/eval): introduce Upvalues struct in closures & thunks
This struct will be responsible for tracking upvalues (and is a
convenient place to introduce optimisations for reducing value clones)
instead of a plain value vector.

The main motivation for this is that the upvalues will have to capture
the `with`-stack fully and I want to avoid duplicating the logic for
this between the two capturing types.
