To speed up compilation times, jumbo allows files to be compiled
together. This is a well known method ("unity builds") to both
compile faster and create a poor man's "full program optimization".
We are only interested in compile times.
Background:
https://chromium.googlesource.com/chromium/src/+/master/docs/jumbo.md
Note that jumbo builds are not enabled by default. To try this out,
add use_jumbo_build=true to your GN args.
