- [x] Add three public fields to the "BoundVariable" service type: declarationTokenPos, visibleStartTokenPos, and visibleEndTokenPos. (naming suggestions welcome!)
- [x] Extend LocalVarDescriptors to hold the declaration token position (it already had the scope visibility boundaries).
- [x] Extend ContextScope to hold the declaration token position.
- [x] Add a unit test which verifies this works for local variables, function parameters, and closure captured variables.

- Use TokenDescriptor instead of intptr_t for all token positions.
- Use TokenDescriptor in raw_object instead of int32_t.
- TokenDescriptor is a POD with an int32_t (this shrinks the size of AST and IR nodes by 32-bits on 64-bit architectures).
There are some cleanups I plan on doing as a follow up CL:
- Replace TokenDescriptor::value() with TokenDescriptor::TokenPos()

- Associate flags with the isolate on creation.
- Dart_CreateIsolate and associate callback do take an

async. These functions contain a so-called async closure (with the actual body)
that should not just return when encountering a return statement, but rather call
the completer first and then return (null).
Previously the last return node has been replaced with a completer.complete call.
This does not work for return statements in nested blocks or try-catch-finally
blocks.
Instead of replacing return statements we now call the completer after
resolving all steps necessary for return nodes, i.e., right after inlining all
finally blocks.
We also need "continuation" returns later on that do not complete the
completer. We differentiate by whether a return node has its scope set or not.

The print-ast output is useful for debugging front end issues. It is a mix
of fully-parenthesized prefix notation (i.e., Lisp S-expressions) with some
infix.
It is not valid S-expressions for various other reasons. Most obviously, it
uses ' (single quote) instead of " (double quote) to delimit strings.
This change makes the print-ast output a valid Scheme S-expression. It can
be pretty printed by copying it, quoting it (by preceding it with a single
quote), and evaluating it at the REPL of a Scheme implementation.
Also, the AST node pretty names are changed to predictably match the class
name. It doesn't seem helpful to have them be arbitrary.

The Name function is used for pretty printing except that for a few
node types we rely on a specific name for implementation correctness.
Overriding the pretty printing function to get out a type name, or a
variable name, or an operator symbol name, is risky.
1. Code that relies on the semantics of the name will break if the
pretty name is changed.
2. Pretty printing is less useful. For instance, LoadLocalNode just
prints the variable name (twice, once as the AST constructor and
once in quotes as the variable name). This is confusing if the
variable happens to have the same name as one of the other pretty
names, e.g., args or seq.
Now, there is a virtual function to get the pretty name but classes do
not change it to communicate other information (type names, variable
names, operator names).

This change adds code that detects if an expression can definitively
never be constant. We use this to analyze the initializer expressions
in const constructors. This check is not entirely water tight, but
together with the checks in canonicalization code catches most
illegal initializer expressions.
The const constructor of class Symbol turns out to be illegal. The
name verification check can't be part of the constructor code.
