node:v12.11.0

There is inconsistent ordering for named capture groups from v12.10.0 to v12.11.0. It appears that versions that came before v12.11.0 ordered the keys by the way they were ordered in the regular expression. v12.11.0 seems to sort the keys.

const r = /(?<BKey>.+)\s(?<AKey>.+)/;
const s = 'example string';
// node v12.10.0
r.exec(s).groups;
// { "BKey": "example", "AKey": "string" }
// node v12.11.0
r.exec(s).groups;
// { "AKey": "string", "BKey": "example" }

Interesting – my understand of the spec would indicate to me that the former behaviour is correct: https://tc39.es/ecma262/#sec-regexpbuiltinexec

Original commit message:

    [regexp] Fix the order of named captures on the groups object

    Named capture properties on the groups object should be ordered by the
    capture index (and not alpha-sorted). This was accidentally broken in
    https://crrev.com/c/1687413.
