2022-08-31 r/4551 feat(tvix/eval): compile `with` expressionVincent Ambo3-11/+65
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.

Straightforward implementation, evaluating the elements of an inherit and preparing the stack so that `OpAttrs` sees all relevant values when constructing the attribute set itself. The emitted instructions for inheriting a lot of values from the same attribute set are inefficient, but it's too early to say whether this actually matters.

Using `OpAttrSelect`, the ? operator will fail when encountering a nested value that is not an attribute set. This however breaks valid code, such as: { bs = 42; } ? bs.a.b 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.
