* refactor: simply browserslists defaults overwriting
When `hasTargets` is `false`, `targets` is always an empty object by definition, `objectToBrowserslist({})` always return `[]` therefore we can remove `objectToBrowserslist`.
* test: apply external-helpers on preset-env test fixtures
* test: add ie 6 to force all transforms in corejs 3, debug, corejs 2 fixtures
* Add ie 6 as targets for test fixtures
* Run exec tests in fresh contexts
* Reevaluate modules in every context
* Cache module code when running tests
* Eliminate weakmap accesses as much as possible
* Remove old multiline usage
* Using bundled polyfill to significantly increase performance
The individual requires for each file were the part that was sooooo slow.
* Drop LRU cache size
* Fixes
* Fix test

I really don't like this commit, but import() is currently breaking
our publish script.
When "normal" tests we are transpiling import() so that it works
with Jest. We can't do it while publishing because we need to
publish the untranspiled import() so that it can load real .mjs files.

When users see errors like

Duplicate plugin/preset detected.
If you'd like to use two separate instances of a plugin,
they need separate names, e.g.
plugins: [
['some-plugin', {}],
['some-plugin', {}, 'some unique name'],
]
```
It can be difficult to determine the source of the conflict, especially
in a larger build system.
This commit outputs what is known about the plugins that actually
conflict, which can be helpful for users to determine the root cause of
the conflict.

Instead of using `convert-source-map`'s `removeComments` method before
parsing the file, we can first parse the file with `@babel/parser` and then
analyze the comments.
This is needed because it is not possible to reliabily detect comments in
JavaScript without fully parsing the file:

* Fixed null error in plugin opts and added a test for it
* Remove !opts and add opts === null check to avoid confusion with false and undefined cases
