The literal_only_boolean_expressions analyzer hint flags this code:
while (true) {
...
if (cond) break;
...
}
=> This is very common code.
The unnecessary_await_in_return analyzer hint flags this code:
Future foo() async {
...
return await foo();
}
=> Addressing this hint by removing the `await` changes semantics,
performance characteristics and async stack traces.

This hint flags code such as
int time = watch.elapsedMillisecond;
and encourages using `var` everywhere:
var time = watch.elapsedMillisecond;
Though if the type is not obvious to a developer, we should be allowed
to write it.
Furthermore it copies the rules from
`package:pedantic/analysis_options-1.9.0.yaml` to avoid being
automatically opted-in to new rules when a new package:pedantic
gets rolled into the SDK.

This change actually migrates vm/dart/* tests to NNBD by fixing
compile-time errors and adjusting tests where needed.
vm/dart/null_float32x4_simd_ops_test and vm/dart/null_float64x2_simd_ops_test
are deleted as they are superseded by static type checks.
vm/dart/regress_40462_test.dart is a huge source code auto-generated
by fuzzer and migrating and maintaining this source doesn't have much
value, so it is deleted.
There are still failures in strong mode due to dependencies on
the packages which are not migrated yet (https://github.com/dart-lang/sdk/issues/42146).

This change forks the benchmarks for the null safety feature where there
now is a null safe version at benchmarks/Foo/dart and a legacy Dart 2
version at benchmarks/Foo/dart2. This change allows benchmarks to be
migrated per go/dart-nnbd-benchmark-migration.
Additionally this change pins the internal benchmarks which have been
moved into their own repository and is now versioned along with the Dart
SDK.
The dart2 implementation will be benchmarked instead of the null safe
dart implementation as of this change. The null safe dart implementation
will be used when null safe benchmarking is turned on.

This is in preparation for upcoming optimizations to the UTF-8 decoding.
The data files are extracts from Wikipedia with markup stripped. They
cover 6 representative cases of typical input data:
- English text, only ASCII
- Danish text, mostly ASCII, only Latin-1
- Slovak text, mostly ASCII, not only Latin-1
- Russian text, max 2 bytes per character
- Nepali text, max 3 bytes per character
- Chinese text, full character range
Each of the languages are benchmarked with small (average 10 bytes),
medium (10 000 bytes) and large (10 000 000 bytes) inputs.
Only allowMalformed: false is benchmarked.
