Package js_shared:
This code is a compile time dependency of dart2js and DDC. It is imported as
a package: import by both compilers.
There is an exact copy in the SDK of the libraries in the
pkg/js_shared/lib/synced sub-directory.
Those libraries are imported as dart: imports by the dart2js and DDC runtime
libraries.
Important: all code under pkg/js_shared/lib/synced must be kept in sync with
the runtime (in sdk/lib/_internal/js_shared/lib/synced) at all times. The
test/in_sync_test.dart test verifies this.
