Try fine grained dependencies.

[davidmorgan]

The analyzer entrypoint used by build_runner doesn't have a way to enable fine grained dependencies, copy build_resolvers.dart locally to set the flag to true, not for merging!

Doesn't work :) I guess the setup is not correct yet, or build_runner is doing something unexpected.

Simplest test that fails seems to be, in build_runner

dart test test/build/resolver/resolver_test.dart -p vm --plain-name 'New resolver updates following a change to source'
E _ResolveSourceBuilder<Null> on web/main.dart:

pretty much the same exception just building one of the benchmarks on the command line.
