The benchmarks were using a range of antipatterns that did not do what
the authors thought they did. It seems that the authors thought the
warmup method has to run for a while and do the full warmup, but the
truth is that the harness will do that for you by running the warmup
function in a timed loop. Instead these patterns just wasted time by
making the warmup more expensive and complex than needed.
This change just removes the warmup overrides since none of them do
anything positive. This change prepares us for future improvements to
the benchmark harness.

Also:
* Clean up lints in both unmigrated and migrated versions of benchmarks.
* Cache lists in local variables in Uint8ListCopyViaLoopBenchmark and
Float64ListCopyViaLoopBenchmark to make the same number of field
accesses as in other benchmarks, in order to make comparison between
different ways of copying typed data more fair.

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.
