This is closer to [the design](https://github.com/carbon-language/carbon-lang/blob/trunk/docs/design/expressions/indexing.md?plain=1#L55-L64), just lacking `ref`, but does remove a lot of special-casing done for the lookup. The `ErrorInst` changes in `Build*Operator` are to align with what was being done for `IndexWith`; don't do an interface lookup if the relevant operand is an error. Otherwise, that becomes visible because some files have an error operand and don't provide the interface.
