Unary operator applications are thunked which can easily be observed by
nix-instantiate --eval -E '[ (!true) (-1) ]'
Unfortunately, there are few simple expressions where this makes a
difference in the end result. Thus it only cropped up when using nixpkgs
for cross compilation: Here we would compile the expression
!(stdenv.cc.isGNU or false)
to assemble python3Minimal's passthru attribute set (at least this seems
to be the most likely explanation from the backtraces I've studied).
This means that an unthunked
<stdenv.cc.isGNU or false>
OpForce
OpInvert
would be performed in order to assemble this attribute set, causing
stdenv.cc to be evaluated too early, causing an infinite recursion.
Resolves b/273.
It seems that having a test suite that doesn't use --strict and relies
on thunks rendered as <CODE> would be beneficial for catching such
issues. I've not been able to find a test case with --strict that
demonstrates the problem fixed in this CL.

This will prevent tvix from printing any warnings.
As a followup, we can also thread this parameter through into the

mapAttrs, map and genList call Nix functions provided by the caller and
store the result of applying them in a Nix data structure that does not
force all of its contents when forced itself. This means that when such
a builtin application is forced, the Nix function calls performed by the
builtin should not be forced: They may be forced later, but it is also
possible that they will never be forced, e.g. in
builtins.length (builtins.map (builtins.add 2) [ 1 2 3 ])
it is not necessary to compute a single application of builtins.add.
Since request_call_with immediately performs the function call
requested, Tvix would compute function applications unnecessarily before
this change. Because this was not followed by a request_force, the
impact of this was relatively low in Nix code (most functions return a
new thunk after being applied), but it was enough to cause a lot of
bogus builtins.trace applications when evaluating anything from
`lib.modules`. The newly added test includes many cases where Tvix
previously incorrectly applied a builtin, breaking a working expression.
To fix this we add a new helper to construct a Thunk performing a
function application at runtime from a function and argument given as
`Value`s. This mimics the compiler's compile_apply(), but does itself
not require a compiler, since the necessary Lambda can be constructed
independently.
I also looked into other builtins that call a Nix function to verify
that they don't exhibit such a problem:
- Many builtins immediately use the resulting value in a way that makes
it necessary to compute all the function calls they do as soon as
the outer builtin application is forced:
* all
* any
* filter
* groupBy
* partition
- concatMap needs to (shallowly) force the returned list for
concatenation.
- foldl' is strict in the application of `op` (I added a comment that
makes this explicit).
- genericClosure needs to (shallowly) force the resulting list and some
keys of the attribute sets inside.
Resolves b/272.

This feature allows the compiler to detect situations where the
created thunk is useless and can be merged into the parent chunk
instead.
The only case where the compiler does this initially is when
statically optimising a select expression.
For example, previously the expression `builtins.length` compiled into
two thunks:
1. An "inner" thunk which contained an `OpConstant` that had the
optimised `length` builtin in it.
2. An "outer" thunk which contained an `OpConstant` to access the
inner thunk, and the trailing OpForce of the top-level program.
With this change, the inner thunk is skipped completely and the outer
chunk directly contains the `length` builtin access.
This can be applied in several situations, some easier than others,
and we will add them in as we go along.

This operation is blocking, so it should be run inside a blocking tokio
task. Tokio panics if it detects a blocking operation inside a non-
blocking task, so cl/8619 would cause it to panic (as the GRPC clients
use spawn_blocking under the hood).
As spawn_blocking moves, and we can't clone `TvixStoreIO` (see cl/8614),
we create a new instance of TvixStoreIO inside each loop iteration.

This switches tvix-cli over from using `NixCompatIO` to `TvixStoreIO`.
For now, we simply instantiate in-memory services instead of getting
fancy with constructors inside tvix-store, but long-term, we might want
to support some URI syntax, to make this configurable at runtime.
nixpkgs eval tests might be fine (and fast!) with a purely in-memory
backend, but other usages might involve talking to a local tvix-store
over gRPC (using the gRPC client, either unix domain socket or even
further away remote), or running tvix-store in "embedded" mode (using
another client than the gRPC client).
