When running in an iframe without specific flags, DDC may not have access to `localStorage`. In this context, even trying to access `window.localStorage` can cause an exception in the iframe.
Wrapping the check in a try/catch allows us to safely check for access before using it.

* Normalize white space around source code strings before producing

* Write an empty line between the source code and diff text in

* Run dart format on all test files.
With these changes you should be able to run the hot reload suite with
`--diff write` and dart format the code multiple times without
introducing changes in the file.

Enums are now split between pre and post canonicalization members. A
separate operation during link-time is emitted for every const
enum field. These are required during link time since enhanced enums can have non-trivial type hierarchies.
Example for snippet:
```
enum E {
e1(1), ...
const E(this.i);
final int i;
}
```
Used to emit enum fields as:
```
dart.defineLazy(CT, {
get C1() {
return C[1] = dart.const(Object.setPrototypeOf({
[_Enum__name]: "e1",
[_Enum_index]: 0
i: 1
}, E.prototype));
},
}
```
Now emits them as:
```
// Declaration-time
dart.defineLazy(CT, {
get C1() {
return C[1] = dart.const(Object.setPrototypeOf({
[_Enum__name]: "e1",
}, E.prototype));
},
}
// Link-time
dart.extendEnum(dart.const(Object.setPrototypeOf({
[_Enum__name]: "e1"
}, E.prototype)), {
i: 1,
get index() {
return E.values.indexOf(this);
}
});
```

Tearoffs are now represented as a closure that resolves an underlying bound context and property on access. `_boundMethod` and RTI getters must also be evaluated late.
Additionally, we now both canonicalize static methods and tag them with their types at class-declaration time (though lazily) - so that late resolved closures have access to their types.
Some tests have been updated to expect simpler errors. DDC traditionally emits slightly different errors that might aid in debugging.

Some CFE lowerings (e.g. pattern lowerings) result in nested scopes containing VariableDeclarations with the same 'name'. The current DDC transform translates these to the exact same name in JS leading to incorrect semantics.
The `TemporaryId` mechanism automatically renames any variables with the same name that would shadow each other. So we re-use that here to ensure the variables all have a unique name if the CFE hasn't already given them one. If the name is already okay (i.e. not shadowing something else), the name in JS will appear unchanged.
Side note: In a future change perhaps we should rename `TemporaryId`. The general mechanism it implements is more useful than its original intended use.

In the flattened control flow state machine generated for dart2js and ddc async functions, there is a single error state variable per function. However, functions can have nested error handling that may try to access stacked errors separately. When we enter a nested try/catch we should avoid clobbering the outer exception as the outer handler may need it later.
To fix this we maintain a stack of errors that we 'push' to when we enter a new try/catch and which we 'pop' from at the end of executing that try/catch.

This restructures all fields as accessor/value-store pairs, providing a level of indirection required for hot reload.
Major updates include:
- All fields (top-level, lazy, virtual, etc.) now have a value store (represented as a private top-level symbol). The value store is initialized on first access for the initializer.
- Lazy value stores are prefixed with '_#v_' to indicate that they are not replaced on a hot reload.
- `declareClass` and `declareTopLevelProperties` are introduced to append classes/members to libraries. These functions extend the 'original' entity/class with fields introduced by a properties object, ignoring the special lazy value stores mentioned above.
- `defineLazy` is replaced with the above operations.
- Virtual/instance fields are still initialized by inside their constructor on first load (so their getter forwards to its value store). On hot reload, however, uninitialized fields are lazily initialized.
- Final fields now use a sentinel value to check for late initialization errors during the initialization loop.
- The JS AST is extended to support class properties.
