This fixes some possible issues with `assert.throws` and `assert.rejects` in combination with an validation object. It will now properly handle primitive values being thrown as error. It also makes sure the `generatedMessage` property is properly set if `assert.throws` or `assert.rejects` is used in combination with an validation object and improves the error performance in such cases by only creating the error once. In addition it will fix detecting regular expressions from a different context such as n-api that are passed through as validator for `assert.throws` or `assert.rejects`. Until now those were not tested. PR-URL: https://github.com/nodejs/node/pull/20482 Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Michaël Zasso <targos@protonmail.com>
