This temporarily reverts back to using @babel/runtime/helpers/* rather
than @babel/runtime/helpers/builtin/*, since some helpers (for example,
`slicedToArray`) were using code patterns that cannot be made to work via
polyfills in older browsers, e.g.
if (Symbol.iterator in Object(arr)) {...}
to test whether `arr` is iterable.
Note that we have to keep both babel-runtime and @babel/runtime for the
time being, since isopackets are compiled by an older (non-beta) version
of Babel that still generates babel-runtime imports.
While running the tests three times might make a lot of sence in CI
environments, it certainly slows things down in development, especially
when you've failed a test on purpose, but still have to wait for it to
run three times to get the output.
This not only implements the `--retries` flag, but also activates it in
both CircleCI and AppVeyor test suites.
Most of the work to prepare for this change was done through the
excellent work of @hwillson in meteor/meteor#9173 which, after some
re-working to support the 64-bit architecture on Windows platforms,
landed in meteor/meteor#9218, making this change as simple as bumping
the minor version number (and rebuilding the dev bundle).
From this point forward, and due to Mongo's discontinuation of 32-bit
support in newer versions of MongoDB, 64-bit platforms will, in
development, use newer versions of Mongo while 32-bit architectures
will remain at 3.2.x versions.
Of course, in production, apps are free to use whichever version of
Mongo they would like, provided that version is supported by the
Node Mongo driver and Meteor's Mongo data packages. At this time
there is no target for when Meteor will stop supporting Mongo 3.2,
but developers are encouraged to take steps to upgrade their Mongo
deployments (through their database providers) to newer versions
since Mongo has set September 2018 as the "End-of-Life" for Mongo
3.2.x. For more information on Mongo support cycles, see their
support documents at https://www.mongodb.com/support-policy.

While this was necessary in previous versions of Meteor, as of 1.6 the
`self-test` tooling will automatically install the dependencies it needs
at runtime.
Not only does this allow the installation to be avoided when tests using
those facilities aren't invoked, it also allows us to reliably install
the same version of these npms, rather than falling back to the
`latest` npm tag on each CI run.
This code had been used to compile the previous generation of
the Windows installer, `InstallMeteor.exe`, however it has been
replaced with the `meteor` Chocolatey package.

Currently, three 'dynamic import' tests exist in the self-test suite:
* dynamic import(...) in development
* dynamic import(...) in production
* dynamic import(...) with cache
These tests take quite some time to run; each test takes ~5 minutes.
While it's great to test them in a faster environment (Unix), which
Meteor will continue to do, the overall value of the three separate
tests is not as great in a slower testing environment, like Windows.
While 'cordova-lib' used to live in 'dev-bundle-tool-package.js' where
it was pre-bundled into the "dev bundle", that is no longer the case.
It is now automatically installed, on demand, when Cordova is used.
This follows up on meteor/meteor#9213, which added it back to the
'dev-bundle-tool-package.js' and updates it in the new location.

Even with $ErrorActionPreference, PowerShell won't automatically fail
when an external command fails with an error code. This explicitly
checks those exit codes and throws an error when that occurs.
Hopefully prevents false successes like that shown in this AppVeyor
test run: https://goo.gl/xxRsF9.
Though it was thought to be reliable when running through 'self-test' on
Windows, it's yet to be seen how reliable.
The worst thing that could come of adding Windows testing would be that
we have test failures again after such a string of green checkmarks and
confidence.
Also, reordered.
