This prevents them from being called dynamically.
Moreover, it prevents asFunction from being called on a non-NativeFunction type argument, simplifying the amount of manual checks.
Note that this CL had to change the CFE and analzyer, and their tests (including mock_sdk) as well.
This can potentially be a breaking change, as the extension methods are only visible when `dart:ffi` is imported, while methods on objects are always visible.

When the test runner runs a legacy test with the non-nullable experiment
enabled, this passes an extra command line flag to tell analyzer to
treat the test library as opted out of NNBD.
This CL also removes the guard that made the test runner skip all legacy
tests when running analyzer with the non-nullable experiment enabled.
We want to run those tests now and (when analyzer supports the new
command line flag) they should be correctly treated as opted out.
This change also removes the tests package config file since that no
longer needs to be used to set the language version. It also removes the
code to generate a package config for the multitests. This CL replaces
both of those mechanisms.

Sign extension of small integers is not symmetric between register arguments and register return values.
On Linux/MacOS x64, the caller is responsible for both the arguments and return value.
Previous tests only tested equality, which tests the equality of the lowest byte. However, when printing or using the small ints arithmetic all 4 bytes are used. The new tests pass back the number in a different format.
The callback tests test the number in Dart, so they did not suffer from implicit conversions. (TestTakeMaxUint8x10 in runtime/bin/ffi_test/ffi_test_functions.cc and tests/ffi_2/function_callbacks_test.dart.)

Now, when writing an AOT snapshot in bare instructions mode, only
the actual instructions in the RawInstructions payload are serialized
instead of the entire RawInstructions object.
Since there are no longer RawInstructions objects in these AOT
snapshots, we also change how Code objects are serialized. Instead
of just containing a reference to the RawInstructions object, we
serialize two pieces of information: where the instructions
payload for this Code object begins and whether there was a single
entry for the instructions payload. (To save space, the single
entry bit is serialized as the low order bit of the unchecked
offset, which was already being serialized).
While we also need the length of the instructions payload, we
approximate it for all but the last Code object by subtracting
the next Code object's payload start from this Code object's
payload start. For the last Code object, we assume it extends
to the end of the instructions image.
Changes on flutter gallery in release mode:
armv7: instructions size -2.70%, total size -1.73%
armv8: instructions size -6.04%, total size -3.63%

So far tree shaking was removing fields which are not used at all.
This change improves tree shaking of fields so fields
which are only written or used as interface targets can be removed.
The following limitations apply:
* Field is not removed if there is a constant object with that field, as
it may impact identity of constant objects which is an observable
behavior.
* Field is not removed if it has a non-trivial initializer as it may
have side-effects.
* Late final fields are not removed, as writing such fields may have
side-effect.
* When field is removed, we may need to introduce an abstract getter
or abstract setter if field is used as a target of an interface call.
If a field was written, then setter would be non-abstract (but empty).

It is possible for an abstract member to be overridden with another
abstract member with different signature (that has, for example, more
optional parameters). In such cases, the noSuchMethod forwarders should
be generated for each distinct signature.
Closes#40248.

The fuzzer found an issue where clamping negative zero would result in
conflicting answers depending on whether or not the clamp operation had
been optimized in JIT mode.
The MINPS and MAXPS instructions will always return the second operand
if the values being compared are -0 and 0, which is the opposite of what
the C implementation of clamp was doing.
Fixes https://github.com/dart-lang/sdk/issues/40426.

The NNBD migration required making subtle changes to some dart:io
semantics in order to provide a better API. This change backports these
semantic changes to the unmigrated SDK so any issues can be discovered
now instead of blocking the future SDK unfork.
The Process class will now throw a StateError if the process is detached
upon accessing the stdin, stdout, stderr, and exitCode getters.
The Socket class will now throw a SocketException if the socket has been
destroyed or upgraded to a secure socket upon setting or getting socket
options.
