This change enables
dart run --enable-experiment :main # When using the package:binary
syntax
This is done by disabling snapshotting when experiments are enabled. We don't have a mechanism for invalidating snapshots based on the set of experiments.
And
dart run --resident main.dart # When using the resident compiler.
Here the issue was that the experiments was passed in a wrong format to the resident compiler process.

* Add an `targetOS` argument to `pkg/vm`'s `compileToKernel`,
that contains the target operating system's name.
* Add a new `--target-os` command line argument for all binaries
that use `compileToKernel` for clients to provide the target
operating system, if known.
* Add a new`"vm:platform:const"` annotation to certain field and
getters in the Platform class.
This annotation is used to annotate static getters and fields with
initializers where the getter body or field initializer must evaluate
to a constant value if the target operating system is known. This
annotation may be used outside the Platform class and in user code.
For example, this annotation can be used on a static `String` field
that is initialized with one value if `Platform.isWindows` is true
and to a different value if `Platform.isWindows` is false.
Note: If the const functions experimental flag is disabled, then
any annotated static methods can only contain a single expression
whose value is returned. If it is enabled, then the static method
is evaluated as if it is a const function with the special
handling of annotated static fields and getters above.
* Create a VM constant evaluator that evaluates uses of static getters
and fields marked with the above annotations when a target operating
system is provided.
* Use the new VM constant evaluator in the unreachable code elimination
transformer.

This CL:
* Adds a benchmark of running `dart analyze` on a single small file.
* Adds a benchmark of running `dart analyze` on a single project.
* Adds a benchmark of running `dart analyze` on several projects.
* Adds a hidden flag to `dart analyze` so it reports ram usage:
run via `dart analyze --format=json --memory` and the memory
usage will be reported in the json output.
All the bencmarks run without and with cache for speed testing, and
without and with cache when measuring memory usage.
The idea of running this via `dart analyze` instead of running either
the script or the snapshot is to measure the "real world" speed which
could be different (although in practise it _does_ just run the
snapshot).
Future CL(s) should also add benchmarks for queries using the
language server.

- Flip flag to make strong null safety the default
- Remove code that auto detects null safety mode from source files,
it is necessary to specify --no-strong-null-safety to opt out.
- Retains sniffing of AOT/JIT snapshots and kernel files to determine
null safety mode, the opt out has to be done when generating these
file.

To prepare for the eventual removal of Observatory, we plan on disabling
Observatory by default while providing an escape hatch to manually serve
the tool for some period of time before completely removing Observatory
from the SDK. This change adds flags that can be used to configure
whether or not Observatory is served.
Currently, '--serve-observatory' is the default behavior, but will be
changed to '--no-serve-observatory' once tooling is ready to support the
escape hatch behavior.

* Move parsing functions to static methods of the classes that
represent the data being parsed.
* Move calculations for adjusting offsets in load commands into the
corresponding classes.
* Make function to insert a new payload segment an instance method
of MachOFile.
* Remove unnecessary abstractions and definitions for MachO load
commands that we don't need to parse.
These refactorings are being done to make later changes easier to
review, by first lifting the initial refactorings out into a
separate CL.

Dartdev will use the user's home directory to store the server information and will keep a directory for cached kernel files in each dart package's .dart_tool directory and in the .dart directory for stand alone dart programs.
This functionality is accessed by providing the --resident flag to the Dart CLI, and the server can be manually shutdown with the new shutdown command.

`log` was previously initialized after argument parsing had already
taken place, which caused an exception when an invalid flag was passed
to DartDev as `log` was referenced in the `dart fix` command
description, which is accessed when building the usage message.
Also fixes a minor test failure related to usage line lengths not being
set correctly for `dart devtools`.
