CFE, and `required` on named parameters When using the option
--enable-experiment=non-nullable the `isLate` and `isRequired` flags will be set
accordingly on Field and VariableDeclaration nodes.

This CL adds a test (lint_test.dart) that gives errors if using e.g.
"var foo = 42;".
We opted to not use the lint "always_specify_types" as that does
more than what the team voted for.

This change basically consists of these steps:
* Enable the incremental compiler to trace used inputs.
* Translate used libraries into used dill inputs.

From the feature spec: "Part files must be marked with the same version
as their library. They must always be treated the same way as the
library they belong to, so it is a compile-time error if a part file has
a different language level override than its library. It is also a
compile-time error if a part file has no language version marker,
and the importing library does".

When we perform constant evaluation in the CFE, the async transform
runs after constant evaluation. Thus, it can no longer use const
bool.fromEnvironment("dart.vm.product") to query whether the VM is
in product mode.
Instead, it can read the product mode define directly from the
environment defines given to the CFE and generate different code
depending on the value.

A kernel library will say it has the newest language version if no
language version is set.
This basically preserves the current semantics of always being on the
newest version (if nothing is explicitly done), e.g. if creating a kernel
library by hand and not setting it.
The front_end also utilize this and just doesn't set it, if it isn't set.

Previously, flow analysis was using the `_identity` state for two
purposes:
1. As the "if true" state for "false" and the "if false" state for
"true".
2. As the base state for the "break" and "continue" code paths of
loops, before any "break" or "continue" statements had been seen.
For the first purpose, it is more consistent to use
`_current.setReachable(false)`. This ensures that in code disabled by
`if (false)`, promotions are not lost. For the second purpose, it is
easier to just use `null` as the base state.
There is a small behavioral change: previously in unreachable code, if
we used the `_identity` state, all variables were considered assigned;
otherwise they were considered assigned or not according to the state
of the code prior to the branch point that caused the variables to
become unassigned. Now, unreachable code consistently has the latter
behavior.
