See https://github.com/tc39/proposal-regexp-named-groups
for a high-level description of the feature and examples. This is one of the
features requested in https://github.com/dart-lang/sdk/issues/34935.
This is a partial implementation because while there is a way to retrieve
groups via Dart by name, it requires casting the returned Match to the
new RegExpMatch interface to avoid changing the RegExp interface.
Changing the RegExp interface will happen in a future update, since there
are other planned changes to the RegExp interface coming soon and that way
we only change it once. See https://github.com/dart-lang/sdk/issues/36171
for more details on the planned changes.
Also, since only BMP regular expressions are supported, not full
Unicode ones (i.e., those with the /u flag in ECMAscript), \k<NAME>
will only be parsed as a named back reference if there are named
captures in the string. Otherwise, the \k will be parsed as the identity
escape for backwards compatibility. The new tests illustrate this
difference.

Fields are not currently getting reset after the 2nd time, unless the

rather than defined fields, which is more difficult to clear.

This allows developers to have more fine grained control over socket
options supported by their platforms, particularly when there is not a
nice way to encapsulate differences between IPv4 and IPv6 options (as
with IP_MULTICAST_IF and IPV6_MULTICAST_IF). It also begins the work
of exposing socket level and option values, although keeping it for now
only to a minimum necessary to assist with setting the multicast
interface for datagram sockets.
This CL also marks `multicastInterface` as deprecated.

This happened using APIs like `Stream.first` that set cancelOnError when
they called `Stream.listen()`. If an error is signaled, Stream internals
will call `cancel()` and wait for that future to complete before sending
the error to the resulting Future. However the `async*` implementation
class did not properly account for that possiblity, and never completed
the cancellation future in that case.

The new file pkg/dev_compiler/lib/src/analyzer/driver.dart handles
building the linked summary for a build unit, and then is capable of
doing analysis using LibraryAnalyzer.
The algorithm is very similar to analyzer_cli's build mode. The
biggest difference is that `dartdevc` has existing support for
discovering source files from the explicit source list (rather than
requiring every source to be listed on the command line). We don't want
to break that support, so there's a bit of logic to follow imports,
exports, and parts.
After the linked summary is produced, DDC gets the analysis results
(errors and resolved AST) for each library, and compiles it into a JS
module.

This adds a method to the internal SDK runtime library that can be
called to clear state when a hot restart is desired.
This also refactors some of the logic around ignoring type errors,
as we need to ensure we can clear those caches. Also I noticed a bug
where the result of isSubtypeOf was assumed to be non-null, but this
was not the case. The new structure should make this more clear.
(Note: I think we may be able to remove a lot of the code for ignoring
type errors soon.)

mDNS queries (and many other local queries) should be allowed to set
their TTL to 255. This patch enables that on all platforms.
On macOS in particular, a system service reserves the mDNS port. The
socket option SO_REUSEPORT is required in addition to SO_REUSEADDR to
successfully bind there; the flag is also supported on Linux, so this
patch allows it to be used there as well (but prints an error message if
it's used on any other platform).
I could use some guidance as to tests for this - is it support availble
for running tests only on specific platforms?
