The utility class DartTypeComparator allows to compare two dart types
under various assumptions, such as ignoring nullability at the
top-level type node or equating all top types.

The dill file has an index at the end. The last 4 bytes of that index is
a size that indicates how big the file is. This is done to support
concatenated dill files. If the dill is invalid and the size is read as 0
both the VM and the dart kernel reader will go into an infinite loop where
it allocates another list entry on every loop iteration (making the whole
loop not infinate because we will run out of ram soon enough).
This CL fixes the issue by checking the size to be possitive.

Metadata repository might be populated lazily as we are traversing the
component, so it is incorrect to skip empty metadata repositories early
in the serialization process.
Instead we filter empty repositories at the very end - after all nodes
were written out.

Removes the Closure.clone() in sync* by adding an additional closure
around the rewritten sync* function body.
This is a re-worked version of the now reverted:
- https://dart-review.googlesource.com/c/sdk/+/136190
- https://dart-review.googlesource.com/c/sdk/+/144948
This CL includes changes from both the above CLs, in addition to:
- A new 'ShadowRewriter' transformer to do deep rewriting of
shadowed parameters.
Previous versions only rewrote the immediate sync* function, missing
references in nested rewritten functions.
Note: This CL is re-landing largely unchanged since the roll-blocking
issues suspected to be caused by this was later attributed to a
different set of changes.
I have independently re-run all failing external tests to verify
them passing for this CL.

* Throw a specific error on mixed compilation mode; let the incremental
compiler ignore that error when trying to initialize (i.e. it doesn't
initialize from it, but it doesn't show any warning either).
* Allow some mixed mode stuff: Eventually the SDK should be in agnostic
mode, so we should allow mixing agnostic with non-agnostic.
Fixes#41493.

Including the library name/uri in types and member names makes these
unreadable in most cases. This changes that default toStringInternal
to omit the library name/uri but supports a verbose mode that includes
the library name/uri for debugging the rare occasions where they matter.

This is a bare-bones implementation (and test) for having an explicit
toString on all `Node`s.
This can then be extended as-needed to better suit our debugging
purposes. It's not allowed to leak, though.

It was literally only used by one test, and only used a single function
not already defined in minitest. That function was only used in one
place and wasn't very useful, so just refactored to not use it.

Add a flag to the verifier that tells it to assume that full constant
evaluation has been performed. It will then complain about anything
that should not be there after constant evaluation.
Also fix two bugs exposed by the new checks:
- The constant transformer did not visit annotations on type parameters
in function nodes.
- The InstanceCreation constructor did not set the parent pointers of
its children.

Now instead it is printed as "import 'hello.dart'".
At the same time we get rid of a dependency.
