Make intent explicit for classes which are intended as interfaces,
or which are not intended to be subclassed.
Mainly classes which are pure interfaces are marked as such,
and platform-specific classes not intended for subclassing
are made `final`.
The `final` classes includes `BigInt`, which is written to assume
that arguments inherit its private members
(it runs `_ensureSystemBigInt` on arguments).
It also includes the `Expando`, `WeakReference` and `Finalizer` classes,
which are just intended as stand-alone implementation classes for accessing
platform-specific functionality.

`hashCode` requires that equal objects have the same hash code.
However it doesn't (and cannot) require that inequal objects have
different hash codes. Remove the invalid check.
This makes the test pass on dart2wasm, which currently implements
closure hash code as:
// Simple hash code for now, we can optimize later
@override
int get hashCode => runtimeType.hashCode;
Note: this change alone does not make the whole file pass with
dart2wasm, there's another (unrelated) issue which will be fixed

This may not fix all of the tests because it's the language version of
the library where the class is declared that matters, not where the
class is used as a mixin. But most tests have all of their declarations

This change improves the fallback exhaustiveness algorithm so that it
also takes advantage of the old, pre-patterns exhaustiveness logic for
enums. This ensures that the fallback exhaustiveness algorithm won't
seem like a regression to users who are used to the old pre-patterns
behaviour. This required extending the old algorithm to handle
new-style switch statements (which have a different representation
from classic switch statements in the CFE) as well as switch
expressions.
We also turn on the fallback exhaustiveness algorithm by default.
Unit tests can still disable it by temporarily setting the global
variable `useFallbackExhaustivenessAlgorithm` to `false`.
The hope is that this algorithm will be short-lived; we are just using
it so that if we decide to enable pattern support in the near future,
users will experience something that is sound. That is, it may
require `default` or `_` cases more often than is strictly necessary,
but it shouldn't ever allow a non-exhaustive switch in a place where
an exhaustive switch is required.

According to the language specification:
1) When 'break' is executed in the 'await for' loop (in 'main'),
the underlying stream subscription is canceled.
2) When async* function ('consume') has stopped at 'yield' or 'yield*',
and the stream is canceled, the 'yield' / 'yield*' statement returns
without an object. It also means that code in 'consume()' after
the loop is not executed and it doesn't append ")" to the log.
So the test expectations are fixed to avoid expecting trailing ")"
at the log when there is a 'break' out of the 'await for' loop.

Avoid quadratic behavior when multiple chunks fail to
have a line break, and the carry-over string gets repeatedly extended.
In the original chunked conversion code, the chunk handling code retained the trailing, non-line-terminated text of the previous chunk, then eagerly concatenated it with the next chunk in order to continue looking for lines. That's moderately effective when lines are shorter than chunks, and neither are too large.
However, a very long line spread across many chunks would perform repeated string concatenation with quadratic time complexity.
This change gives `LineSplitter` the option of using a `StringBuffer` to collect multiple carry-over line parts.
The buffer is needed whenever a chunk does not contain a line break, and needs to be combined with a previous chunk's carry-over. This avoids ever directly concatenating any more than two strings.
The `StringBuffer` is not allocated until it's first needed, so if lines are generally shorter than chunks, the buffer won't be used. Once allocated, the buffer is retained in case a buffer will be needed again, but cleared when its contents are used.
The code optimizes for the simple case of each chunk having a line break.
