/// where `<filter>` takes the following forms:
///
/// - `all` -- dump MIR for all fns, all passes, all everything
/// - `substring1&substring2,...` -- `&`-separated list of substrings
/// that can appear in the pass-name or the `item_path_str` for the given
/// node-id. If any one of the substrings match, the data is dumped out.
/// - a filter defined by a set of substrings combined with `&` and `|`
/// (`&` has higher precedence). At least one of the `|`-separated groups
/// must match; an `|`-separated group matches if all of its `&`-separated
/// substrings are matched.
///
/// Example:
///
/// - `nll` == match if `nll` appears in the name
/// - `foo & nll` == match if `foo` and `nll` both appear in the name
/// - `foo & nll | typeck` == match if `foo` and `nll` both appear in the name
/// or `typeck` appears in the name.
/// - `foo & nll | bar & typeck` == match if `foo` and `nll` both appear in the name
/// or `typeck` and `bar` both appear in the name.
