@liuxingbaoyu I merged this so we can start building the baseline results for Babel 8, but could change it to run in parallel chunks like for Babel 7? The job takes almost one hour otherwise.

test262 has caching for Babel 8, let's see how long it takes after caching. :)

I'm very confused by caching, I thought it was to cache when the tests change and the Babel code doesn't? 😅

Because if the Babel code changes, how do we know for which tests the cache needs to be invalidated?

Before starting node v0.10 processes, we check the Babel-transformed code and all untransformed dependencies.
Whether Babel changes or the tests change, the cache will detect the changes immediately!
