[vm] Namespace constants like offsets and sizeofs to use runtime_api.h
...
Second sub-CL of https://dart-review.googlesource.com/c/sdk/+/100644
The first was here https://dart-review.googlesource.com/c/sdk/+/103487
Now that offsets_extractor is checked in, and we have a big header full
of hard coded constants, the next step is to make sure everything is
using those constants. This is essentially everything in the original
CL, except the new simarm_x64 architecture.

[vm] Create offsets_extractor tool.
...
First sub-CL of https://dart-review.googlesource.com/c/sdk/+/100644
A big chunk of the original CL is to do with switching anything that tries
to get the offset of a field in a class to do so using constants generated
by offsets_extractor, rather than introspecting the C++ classes with macros.
This CL just checks in the offsets_extractor tool and its output, as well as
a few bits and pieces needed to make it run.

[vm/reload] Make sure classes in saved class table are visited by GC
...
Previously, IsolateReloadContext::CheckpointClasses() was filling
local_saved_class_table with raw pointers to classes and at the same
time it was adding classes to the set which is based on Array.
After that local_saved_class_table was saved into saved_class_table_
were it becomes visible to GC. However, adding an element to the set
may trigger GC in the middle and pointers for already processed
classes in local_saved_class_table are not visited and are not updated
if GC moves a Class object.
Also, IsolateReloadContext::VisitObjectPointers was not visiting
classes in saved_class_table_ properly as it was interpreting it as
an array of saved_num_cids_ pointers (while it is an array of
ClassAndSize elements).
This change fixes flaky crashes in vm/dart/trigger_gc_in_native_test.

[VM] Improve AssertAssignable/InstanceOf by having a fast case for non-generic, instantiated types
...
When the type to test against is instantiated and has no type arguments
there is a high probability that we receive instances of that class or
subclasses at runtime.
This CL therefore extends the fast-path of AssertAssignable/InstanceOf
by checking whether the instance class id is within the cid ranges that
directly/indirectly implement/extend the type to test against.
Currently we have an almost depth-first preorder numbering of class ids
in AOT, but there are exceptions. So each class can have a number of
cid-ranges as subclasses / classes which implement it's interface.
This seems to improve performance of dart-aot-v2
* flutter stock build by 15+%
* DeltaBlueClosures by 10+%
and reduces code size on
* flutter gallery by -3%

Make array allocation stub shared between isolates.

This allows to make the last explicitly named stubs shared between isolates.
When sharing code stubs, we can't do patching at their entry anymore.
Therefore, I had to remove patching support of the array allocation stub.
Is this a functionality we want to keep?
The change is mostly performance-neutral because optimized code has an inlined fast
path for array allocation and only uses the stub for the slow-case.
The only isolate-specific stubs left are object allocation stubs which are
associated with their Class are per-isolate.
Since this CL removes any isolate-specific stubs from StubCode, it becomes AllStatic.

- Track whether class allocation should be traced in existing ClassHeapStats structure.

These changes appear to be performance neutral.
An alternative approach is to deoptimize all code that inlined allocations for a specific class. I do not think this is a good approach because we will spoil the water- allocations that aren't occurring in the (optimized steady state) running program will appear in the allocation profile. This will make the data much less actionable bordering on misleading. The approach used in this CL will guarantee the allocation profile aligns with the actual running program.

Make subtype test stubs isolate-specific.

This avoids loading the current isolate from the context
register and makes those stubs not depend on having the context

1. When reading a full snapshot use the class id from the snapshot instead
...
of generating a new one. This ensures that assumptions made about the
class id when generating a snapshot will still hold in the version that
runs from a snapshot.
2. remove ObjectHistogram code as it is not used anymore and has been replaced
by VM service.
