GH-100987: Don't cache references to the names and consts array in _PyEval_EvalFrameDefault. (#102640) 
* Rename local variables, names and consts, from the interpeter loop. Will allow non-code objects in frames for better introspection of C builtins and extensions.

* Remove unused dummy variables.

GH-98831: Implement array support in cases generator (#100912) 
You can now write things like this:
```
inst(BUILD_STRING, (pieces[oparg] -- str)) { ... }
inst(LIST_APPEND, (list, unused[oparg-1], v -- list, unused[oparg-1])) { ... }
```
Note that array output effects are only partially supported (they must be named `unused` or correspond to an input effect).

(These aren't used yet, but may be coming soon,
and it's easier to keep this tool the same between branches.)

Added a sanity check for all this to compile.c.

gh-100146: Steal references from stack when building a list (#100147) 
When executing the BUILD_LIST opcode, steal the references from the stack,
in a manner similar to the BUILD_TUPLE opcode.  Implement this by offloading
the logic to a new private API, _PyList_FromArraySteal(), that works similarly
to _PyTuple_FromArraySteal().

This way, instead of performing multiple stack pointer adjustments while the
list is being initialized, the stack is adjusted only once and a fast memory
copy operation is performed in one fell swoop.
