- changes top-level/static method tearoffs to work similar to instance
method tearoffs (attach typeinfo at the tearoff location).
- changes getters/setter signatures to a more compact representation.
- fixes incorrect reification of tearoffs in DDC Kernel backend,
causing a couple of tests to pass after the changes.
- module startup should also be faster, because we avoid using
`defineLazyProperty` for signatures.

When enclosingElement is `null` we fail to find the library. There are

This no longer fails on a bogus error (setting a stack on a primitive):
main() async => throw "hi";
Doesn't come up in tests as that path (rethrow) is only exercised for unhandled exceptions.

This disables most runtime features of dart:isolate, similar to dart:io.
For now, this supports `new ReceivePort()` and `ReceivePort.close` as
those are used by async tests to keep the Dart VM alive. Those are
no-ops in DDC. Also removes most of dart:_isolate_helper, except for
the JS API that's used to bootstrap DDC `main()`.

Translate assert statements in async functions. The translation of
the condition subexpression can produce a sequence of statements that
have been hoisted out of it. These need to be guarded so they are
executed only when asserts are enabled.
For this purpose, we introduce an AssertBlock. The semantics of the
assert block:
assert { s0; ...; sn; }
is the same as:
if (assertsEnabled) { s0; ...; sn; }
where assertsEnabled is a more primitive nullary expression that is
true iff. assertions are enabled. We chose not to encode this using a
construct like assertsEnabled because (1) we would have to support it
appearing as an arbitrary expression which we don't currently need
and (2) it requires deeper pattern matching to detect and skip the
guarded code when desired.
The translation is more complicated because if there is a message
subexpression in an assert, it is conditionally evaluated only if the
assert's condition is false.

There are a few bug fixes here as well. Most notably, `.name.name`
instead of `.name` in DDK's analysis of virtual accessors. DDC/K's
handling of spread arguments in JS interop was also fairly broken
(it was generating a RestParameter instead of Spread). There's
also a lot of cleanup in js_ast as well, to make it a bit more
type safe.

For example, hover now works on `async` in `async.scheduleMicrotask`:
import 'dart:async' as async;
main() {
async.scheduleMicrotask(() { print('hi'); });
}
This does not change the import line or types, as neither of those
currently supports hover.

Internally, we will need to enable in our bootstrap code. I'll turn
that on there for now - but perhaps we can make that a per-target thing.

We already do this in most cases when we have a constructor initializer
and the field initializer is side effect free (e.g. implicit null or a
literal). But `this.` fields were not recognized as being initialized
explicitly by the constructor.
This is already working in DDC+Kernel (because `this.` parameters are
desugared).

This change improves DDC/DDK source maps:
- fix Analyzer backend step locations to pass all of the tests
Kernel was passing. Also improves breakpoints and code coverage.
- fix Analyzer backend to mark hover spans where possible, such as
fields, parameters, locals, `this`, properties, methods, etc.
- refactor DDC/DDK backends to emit source locations, rather than
pointers to Analyzer/Kernel tree nodes.
- unify/simplify source_map_printer between Analyzer/Kernel backends.
- source_map_printer understands JS expression nesting, marking the
innermost JS expression offset corresponding to a given Dart offset.
This preserves hover tooltips, even for expressions with implicit
coercions (e.g. `dart.test(x)`)
- source_map_printer understands that JS end-of-function markings need
to be before the closing brace.
- merge _visitAndMarkExpression and _visitExpression to simplify
Analyzer & Kernel backends.
- fix test expectations where the column location was too specific.
- adds a message to the stepping test runner to help future debugging.
- removes optional destructuring support from Analyzer backend. This
was unused/untested and added complexity. Instead we should decide
if/when to fully switch to destructuring, and then do so.
