For example, by default 64-bit architectures now grow as 2, 4, 8, 16 instead of 2, 8, 32.
This change is to reduce memory usage and maximum minor GC time for Flutter and Fuchsia.
It would negatively impact batch applications, which prefer throughput,
so the new defaults are overriden by the command-line Dart VM in
runtime/bin/main.cc

The `@pragma` annotation on `vmservice_io.main` is modified to only mark it as a
root on non-product builds. Since the annotation is evaluated in the constant
transformation, we need to thread a flag through `gen_kernel.dart` indicating
whether the Kernel produced should target a product precompiler.
# Test Plan
Tested locally on Flutter. Unfortunately it's not possible to test the scenario where
`vmservice_io` is not included, since we don't have any "product" bots. Soon the
flag will be introduced into Flutter, and we will have some coverage from there.

In Dart 2.0 AOT compilations we give dart_bootstrap/gen_snapshot the
fully linked Kernel IR file (*.dill file) with evaluated constants.
This CL will make the 2.0 AOT compiler
* only accept .dill files as input
* no longer invoke various functions during startup
* no longer start the VM service
* hit unreachable in DartEntry::InvokeFunction()
