The current output indirectly advertizes premature out-of-order migration,
which would be bad if it happened widely.
We can keep the flag, but should not advertize it.

List.generate could return both growable and fixed-size lists.
This change specializes invocations of List.generate when value of
'growable' argument is known (constant or omitted), so it becomes
possible to infer actual type returned by the factory.
This becomes more important with null safety as List.generate is used
more often to initialize lists of non-nullable elements.

logRecords is expected to be of type dict, but the fallback value
was previously set to [] (type list).
This CL changes the fallback values to an empty dict.
It also uses the builtin dict.get() to handle to fallback instead
of manually doing so.
Note: This CL will not make the bot go green.
It will change it from purple (infra failure due to crash) to red
since there are tests that are legitimately failing.

Generated files can exist outside of `lib`. In a Bazel workspace
these are referred to using `file:` URIs that point to the generated
code directory. We need to be able to resolve references both from
the generated code to non-generated code and vice versa.
This is blocking the use of the migration tool in Bazel workspaces,
since the migration tool doesn't have the same level of error recovery
as the rest of the analyzer, so it needs to be able to resolve all
files including generated ones. But it should also improve the user
experience for using the analysis server in general in Bazel
workspaces, by reducing the number of nuisance "URI not resolved"
errors.

We cannot simply discard the `required` modifier in weak mode function
types since function types that differ in the placement of `required`
cannot compare equal. Instead, we do that during subtype checks.
We continue to ignore `required` in the actual calling convention in
weak mode.

This is a reland of 391d3bcdd8
The root cause of the failure is that the destination path uses forward
slashes as path separator.
This fix checks for forward slashes as a potential path separators.
If both forward and back slashes exist, the one closer to the end of the
path will be used to get the destination directory.
If any step fails, it will fall back to original copy.
Original change's description:
> File::Copy avoids direct copying on Windows

> There is a race condition for copying file on Windows, where CopyFile()
> returns success but data has not been populated into destination file.
> E.g process is killed or died in the middle.

> This cl will change File::Copy as

> 2. Rename the file to the target file.
