This CL introduces an alternative way to calculate scopes for
expression evaluations. Currently the previous method is kept as well.
What this does is that it:
* Finds all nodes that match the offset and uri. (Ideally there's only
one, but that's not always the case --- it's the case for less than
60% of cases in the test added actually).
* Calculate the scope along the way.
* Return the scopes of all the found nodes that offset.
A test that asks for ~all file offsets in the dill files in the sdk and
compares the result with the scope the binary serialization computes is
added.
A single point can't always be found (for all dills in the sdk
only ~58.93% returns a single result), but for each query the wanted
scope is among the results returned.
For the non-outline dills in the sdk, between ~87.93% and ~94.52% of
the results are either a single result or multiple results with the
same actual scope in all of them.
Note that the test asks for ~all offsets, not just "debuggable" or
"stopable" offsets (which will likely vary depending on the vm/web
backend etc) --- likely the percentage will be higher for those points
though.
When this returns multiple results one can likely be picked by the
client based on information it has about names of variables in scope
etc.
Note that the test is rather slow, on my machine with the platforms
available there it makes 3,908,181 queries in ~3.5 minutes.
(Which corresponds to roughly 18,610 per second or under 0.06 ms per
query on average though, so it doesn't seem like a concert for actually
using it.)

Many tests under `pkg`, like `pkg/js_ast` and `pkg/analyzer_cli` are
meant to run as unit tests in the Dart VM. These were also being run in
dart2js and causing flakiness because they took a long time to build on
our CQ.
Locally some of these tests compile in under 5s, but we see the
compile-time vary among the bots a lot. I've observed cases close to 30s
and some that reach the 1-minute timeout cutoff. Flakiness data show
that this is happening between 5-7% of the runs, especially on linux
bots.
This CL stops running these tests on the dart2js configuration by
changing which subset of the `pkg` suite is provided to dart2js. It also
adjusts the .status file to skip a few suites for convenience on local
testing only. This allows developers locally to run `test.py -n... pkg`
without worrying about filtering out skipped suites.
Addendum: after discussions on the CL we decided not to cmpletely drop
coverage of js_ast tests on JS to ensure it can be used in browser
environments in the future. To support this we made made the tests
cheaper by removing the dependency on package:test. They will now only
be run in a single configuration, which is all we need for this purpose.
We can reevaluate and remove this if we continue to see timeouts.

This package contains the logic for building native assets.
This package is the backend that invokes toplevel `build.dart` scripts.
For more info on these scripts see https://github.com/dart-lang/native.
This is a separate package so that dartdev and flutter_tools can reuse
the same logic without flutter_tools having to import dartdev.
Some design decisions:
* We don't yet have `build_dependencies`, so we use the ordinary
dependency graph for ordering of native assets builds. (If there is
a cycle we refuse to run.)
Bug: https://github.com/dart-lang/pub/issues/3794
* Builds are cached based on all the configuration provided by the
caller. Environment variables are ignored in caching. This CL also
contains a unit test that invokes the build by not passing through
environment variables. However, for Windows we need to pass through
at least `SYSTEMROOT` for MSVC to run correctly. So we might need
to further explore if we can/want to lock env variables down.

The purpose of the CL is to enable re-use of the mmap support in dart2js
in other tools (e.g. package:heapsnapshot & package:kernel).
There's a small refactoring to remove zero-termination logic out of the
general mmap support.

This CL is a warm-up to a follow-up change that will make running the
CFE trybot faster.
This CL:
* Rename tests that require git (because when working with filesets
and shards in the test system, the "checkout" is not a git checkout
and git commands thus doesn't work properly.
* Filters the front-end unit test setup on the front-end bot the way
it was probably intended, i.e. run tests in pkg/kernel, pkg/front_end
and pkg/fasta (actually, the last one doesn't exist, but still)
instead of just in folders inside the "suite" 'pkg' that somewhere in
the path has something called 'kernel', 'front_end' or 'fasta'.
* Split unit_test_suites.dart into a "forwarding shell" and a impl.
In a follow-up CL the impl will be converted to nnbd to allow for
using 'required' on named parameters, but if the entry point was
nnbd it would run in sound nnbd mode and nothing would compile
because all imports are not nnbd.
Overall this CL should change very little, mostly just run a few less
tests, i.e. for instance skip tests that live inside a folder called
'fasta' somewhere inside the analyzer directory path.

The tests incremental_dart2js_test and incremental_compiler_leak_test
- taking ~1 minute each locally - often times out at 4 minutes (after
almost being done) on the bots. This CL gives them a little more time
hopefully allowing them to finish.

Note that this is the 2nd try as the first try accidentially had the
extension (.dart) in the status file so they did not apply.

This was causing flaky failures when initializing DDS as it was invoking
the getVM RPC which in turn sometimes accessed the script_uri after it

This CL adds --trace-precompiler-to option which generates a machine readable
precompiler trace (list of all compiled functions and their dependencies).
It also expands package:vm_snapshot_analysis with tools for reading and
analysing this trace.
For example snapshot_analysis explain dynamic-calls command allows
to list all dynamic calls sorted by their impact on the size of the AOT
snapshot.
