Now they are only retained if one of the following is true:
* The parent is Future.wait or Future.timeout.
* The local function is a generated body of an async/async*/sync*
function.
* Symbolic stack traces are enabled.
When a local closure's parent is dropped, the parent name will
be printed as `<optimized out>` in places like exceptions.

Before this CL we could for instance get this result:
```
$ out/ReleaseX64/dart --enable-asserts pkg/front_end/test/fasta/weak_suite.dart -DsemiFuzz=false -DskipVm=true -- weak/general/error_recovery/issue_39058.crash
[...]
1 failed:
weak/general/error_recovery/issue_39058.crash: Pass
```
The reason is, that before it onle rewrote the expectations if there was
exactly one expectation.
`weak/general/error_recovery/issue_39058.crash` for instance (currently)
has two expecations: RuntimeError and SemiFuzzFailure.
All combinations of `-DsemiFuz` and `-DskipVm=true` would thus keep both
of those expectations.
For the combination `-DsemiFuzz=false -DskipVm=true` it actually passes,
though, which doesn't match so it fails saying that the expectations
should be updated.
For any of the other expectations it would be fine because it would get
one of the expected outcomes:
* `-DsemiFuzz=true -DskipVm=true`: Fuzzing is enabled so it would get a
SemiFuzzFailure which matches one of the expectations.
* `-DsemiFuzz=true -DskipVm=false`: Fuzzing is enabled so it would get a
SemiFuzzFailure which matches one of the expectations.
* `-DsemiFuzz=false -DskipVm=false`): It doesn't skip the VM so it gets
a RuntimeError which matches one of the expectations.
This CL fixes the issue by removing the "wrong" expectation(s), leaving
the correct one(s) and adding 'pass' of all other expectation(s) have
been removed.

The buildbucket v1 API is deprecated and may stop working at any time.
This also fixes the buildset tag to use the latest format.

Previously, the ErrorVerifier was checking assignability for any `=`
or `??=` assignment whose LHS was not a simple identifier. But this
case is unnecessary; it's already handled by the resolver.

Previously, if the preview server couldn't be reached because it had
exited, we would generate an error message with an obscure looking
stacktrace. I believe this was prompting users to file bug reports
against the migration tool, when in fact all they needed to do was
restart the migration process. Hopefully this better error message
should help avoid confusion.
I also took the opportunity to improve the error message that is shown
if the user does restart the migration tool but tries to keep
interacting with it using an old authToken.
Fixes#45202.

We currently run our leak tests weekly.
This extends it so we also run leak tests with advanced invalidation,
as well as our strong and weak tests with fuzzing enabled.

In order to implement "why not promoted" functionality for constructor
field initializers, we will need to call
checkForFieldInitializerNotAssignable from the resolver, so that we can pass it
failed promotion information. So move it into the
ErrorDetectionHelpers mixin.

In order to implement "why not promoted" functionality for variable
declaration initializers, we will need to call
checkForInvalidAssignment from the resolver, so that we can pass it
failed promotion information. So move it into the
ErrorDetectionHelpers mixin, along with _checkForAssignableExpression
(which it calls).
_checkForAssignableExpressionAtType can now be private, since all of
its callers are now in ErrorDetectionHelpers.

The implementation of CpuSamples.timeSpan has never matched the
specification and has never been returned properly from the service
(returned as 'timespan' instead of 'timeSpan'). Since timeSpan is
effectively the same value as timeExtentMicros, timeExtendMicros should
be used instead.

I considered doing the bigger refactor I described in the first CL, then
I realized that I can't because the constructors for `ErrorCode` are
`const`. We should still have some kind of tests, but they won't be as
complete as we might hope.
