* In subtype-tests in the compiler, allocate temporary objects in new-space.
* Add local StackZone to avoid accumulating zone memory.
* Exlude "Function" type from this optimization.
Fixes#28318.

Added offsets to more nodes.
Added end offsets to some nodes.
Added functionnode debuggability flag.
This changes the dill format.
The new offsets et al. are read on the C++ side, but not used
for anything usefull yet.
This is step #2 in introducing these things, next step(s) will be
using it on the C++ side.

MirrorsUsed doesn't transitively include reflective information. However, it must still be able to create TypeMirrors for types that are used as return- or parameter types.
Initially, the patch checked that TypeMirrors had the correct number of arguments for generic types. This is now disabled.
A better approach would be to know if a class has full reflective information, or not. But this would require much bigger changes to the system.

- The flow graph builder is only used to visit Statements and
Expressions so it does not need TreeVisitor as a base class. This
will make refactoring it easier.
- The TranslationHelper is bound to a Thread so we do not need
Thread::Current where we have a TranslationHelper.
- BlockExpression does not exist in Kernel any more, so it can be
removed from the C++ AST implementation.

* Basic implementation of reflecting generic types using dynamic list of type arguments
* Removed redundant expectation in test
* Added basic support for dynamic type arguments in reflectType of js_mirrors
* Fixes according to code review comments: major cleanup, added more test cases and updated docs
* Updated JS mirrors reflectType() to match behavior of VM implementation
* Terminate exception messages with a dot; Improved error handling for empty argument list and type checks;
* Use NumTypeParameters when checking provided argument list size
* Check if type arguments are malbounded; added test cases for typedefs and mixins
* Uncommented a test case
* Updated lib.status to mark some tests as failing in dart2js due to limitations in JS mirrors
* Fixed mixin test mock definition; updated configuration for tests requiring checked mode
* Handle nested generic types in type argument parsing (JS)
In some cases when loading a deferred library twice, the VM would crash/throw.
Make sure we generate the correct static NoSuchMethod error when referring to
a deferred library that is not loaded yet.
Fixes#28278.

1a41627ecc caused isolate start up to incorrectly create a second megamorphic miss function when running from a JIT app snapshot. These caused the code for the one from the snapshot to be collected, and the parser to fail attempting to recompile it.

This is a fixed version of c84f30741c90d040254767ff769a40d2cba3fb1a that
resolves issues with comparing uint and intptr_t.
Original Commit Message:
Added tracking of memory usage inside of threads. In addition, the max memory usage is kept track of using a high watermark for both the threads and the isolates. Isolate high watermark information is updated when a thread exits the isolate. The isolate high watermark consists of the sum of all thread high watermarks (including the high watermark of the exiting thread). High watermark information for both threads and isolates is now visible in the isolate view in the Observatory.

The analyzer has a stricter patch parser than the VM. Patch files
cannot change signatures of patched members. Specifically, they cannot
change:
- the return type
- a parameter's name
- a parameter to an initializing formal
- an optional parameter's default value

Added methods to surface number of zone and scoped handles in each isolate. These values are displayed in the isolate view page in the Observatory. These handle counts for the native IO isolate will be surfaced in another CL.

- For now include source uncompressed.
- When running from kernel, use token position 0
(i.e. dummy, but 'real' position) as start and end on functions
and classes to enable Observatory to run with the dill file.
- Debugging does not work, but one can browse the source in
Observatory.

We often do work when adding entries to these maps but when entries already
exist we skip the work. When running the precompiler multiple times we should
clear the maps to ensure we always to the necessary work.

Before, the VM's dart:typed_data was a complete replacement of the SDK's
dart:typed_data implementation instead of a patch. This is unlike all
the other SDK libraries. This difference requires special-casing for
dart:typed_data in tools that handle the SDK libraries (e.g., the
Analyzer's patching support, the GN build).
This change makes dart:typed_data back into a patch to the SDK's
implementation. It reintroduces a distinction between abstract
interface and concrete implementation classes, so there are more
classes.
