In 8f4e5c8194 the `DiagnosticReporter` was cached in
`DevCompilerTarget` which introduced a memory leak.
Unfortunately our weekly bot that looks for leaks has been out of
commission, but is now coming back online.
This CL fixes the leak by overwriting the field every time, meaing we
don't save a reference to the first one (which is a leak).
Maybe ideally we shouldn't save it as a field at all, but that's a
potential for another day.

This change created a CFv2 build target and provided two
implementations of the FuchsiaEmulator, so that I can continually work
on both CFv2 build and test script integration independently.
The v2 target can be built with
```
tools/build.py --os fuchsia --mode release fuchsia_ffi_test_package_cfv2
```
And v2 FuchsiaEmulator implementation can be triggered with
FUCHSIA_CFV2 environment variable.

The change allows const lists to be in the spread of a const set and vice-versa. It also reports the correct error if we use a map in a list/set (and vice-versa) which is necessary when we combine all the error reporting in the `ConstantVisitor` to one location.
Adds some additional tests to make sure the behaviour we want is still working.

The linter is moved from third_party to pkg, and the old copy has
been removed from DEPS for weeks now. Remove the workaround that
ignores an old copy of linter in third_party/pkg/linter.
Users who have updated without running gclient sync -D will
now get an error that they have two copies of the
linter package, and they will get a message that they should
run gclient sync -D when they run gclient sync.
This completes the migration of the linter package into the SDK
source repository.

Currently the heap snapshot tool uses a regular Set<int> for storing
ints between 0 and the number of objects (n).
This CL instead introduces a specialized int set backed by a Uint8List
where each bit represents a number between 0 and n.
This specialized set is then created to fit the number of objects, so
even an empty set takes the same amount of space as a full set: about
125 kb per million possible values (or ~6 mb per 50 million).
For small sets thats a lot worse than before, but for big sets it's a
lot better. Runtime is also a lot better.

Consider for example the following two functions
f0(int value) => value == 0 ? ... : ...;
f1(List<int> list) => list[0] == 1 ? ... : ...;
before this change we would produce a `BoxInt64(value)` followed by
`StrictCompare` in `f0` and `UnboxInt64` followed by `EqualityCompare`
in `f1`. However the decisions should be reversed: when comparing
unboxed values we should lean on `EqualityCompare` and when
comparing boxed values when smis are involved we should lean
on `StrictCompare`.
This change adjusts specialization and canonicalization rules to achieve
that: we prefer to emit `EqualityCompare` when specializing and then
add rule to collapse it back into `StrictCompare` if we discover that
is going to be more optimal (e.g. allows to avoid boxing).

When serializing JS, we can sometimes end up changing the order we visit ModularExpressions. This can mean their indices are not stable against serialization and so the emitted code (and as a result hashes for that code) can change if the compiler did any serializing during the compilation.
We can make the order stable by sorting the holders before we process them.
This removes diff in hashes when running this (`--test-mode` forces serialization):

The analyzer team has decided to adopt the convention of using `TODO`
comments to document long term issues that should persist in the
codebase, and `FIXME` comments to document short term issues that need
immediate attention. They may even consider adding a presubmit hook
to ensure that `FIXME` comments are only used during local
development.
Accordingly, it makes sense to suppress `TODO` comments from being
surfaced to the IDE "problems" view (since there are hundreds of them,
and they're not immediately actionable). This makes VSCode's
"problems" view much more usable in "tree" mode.

We are experiencing diffs in Dart2JS source maps in `--test-mode` which does a serialization round trip. JS that should map to default parameters is instead mapping to the surrounding `Constructor` member since the FieldInitializer's offset is getting dropped.
This is affecting any Dart2JS split action build since those all end of serialiaing and deserializing the kernel. Any other tools using this serialization would also be affected.

When the CFE compiles code for DDC or dart2wasm, it lowers late final
fields to synthetic getters. In order to ensure that accesses to these
fields can still be type promoted, a flag is added to the kernel
`Procedure` class, to indicate that a getter was produced by lowering
a late final field. When deciding whether a property access is
promotable, the CFE checks this flag; if it's set, it treats the
getter like a field.
Includes a language test validating the fix.
