Ryan Macnak 1e24fe7d69 [vm, compiler] Specialize unoptimized monomorphic and megamorphic calls. 
dart-bytecode, arm64:            +4.742% geomean
dart-bytecode-jit-unopt, arm64: +12.73% geomean
dart2js-compile, x64:            +3.635% geomean

In the polymorphic and unlinked cases, call to a stub the does a linear scan against an ICData.

In the monomorphic case, call to a prologue of the expected target function that checks the expected receiver class. There is additional indirection in the JIT version compared to the AOT version to also tick a usage counter so the inliner can make good decisions.

In the megamorphic case, call to a stub that does a hash table lookup against a MegamorphicCache.

Megamorphic call sites face a loss of precision in usage counts. The call site count is not recorded and the usage counter of the target function is used as an approximation.

Monomorphic and megamorphic calls sites are reset to the polymorphic/unlinked state on hot reload.

Monomorphic and megamorphic calls sites do not check the stepping state, so they are reset to the polymorphic/unlinked state when stepping begins and disabled.

Back-edges now increment the usage counter in addition to checking it. This ensures function with loops containing monomorphic calls will eventually cross the optimization threshold.

Fixed backwards use of kMonomorphicEntryOffset and kPolymorphicEntryOffset.

Fixed C stack overflow when bouncing between the KBC interpreter and a simulator.

Aart Bik fa6fce61fa [dart/vm] Improved inlining methods and heuristics 
Rationale:
Previous method cached graph information (instruction and call site
counts) on a per-function level, not accounting for potential
specializations. The improved method runs an extra constant folding
pass, and only caches per-function information for non-specialized
cases. As a result, we inling much better, see for example, the
added test as illustration.

Since we no longer cache for constants, compile-time may be increased
a bit due to the extra scan. In the long run we should consider
for common constant "situations" as the call site.

This resulted in incorrect values being returned from TraceAllocationFor
causing all allocations to go into the slow path. This also caused the

https://golem.corp.goog/Benchmark?team=dart-vm&benchmark=DeltaBlue#targets%3Ddart%3BmachineTypes%3Dlinux-x64%3Bcpus%3DIntel%20Core%20i5

Culprit was ClassTable::StateOffsetFor(intptr_t cid), so this CL

Teagan Strickland 0bcb607868 [vm/compiler] Reland "Fix receiver redefinition type for poly inlining." 
In cases where the same target function is used for multiple
CID ranges, we only perform the inlining once. However, if the
CID range used for the initial inlining is a single CID, we will
set the type of the redefinition to that CID.

Detect this case and clear the concrete type associated with
the redefinition if it was given one.

Alexander Markov 0e6b74543c Revert "[vm/kernel] Use GC-tracked ExternalTypedData/TypedDataView for kernel buffers" 
This reverts commit ab6aeaa106.

Revert "[vm/compiler] Speed up the compiler part which deals with kernel reading up in DEBUG mode"

This reverts commit b316210d94.

Reason for revert: regression of snapshot sizes (DNO-599).

Original change's description:
> [vm/kernel] Use GC-tracked ExternalTypedData/TypedDataView for kernel buffers
>
> Until now we often leaked kernel buffers (e.g. hot reload buffers) because various
> objects were referencing ExternalTypedData objects pointing into the middle of
> c-allocated memory. This made it impossible for the GC to determine when the last
> reference is gone.
>
> This CL ensures that the actual buffers are *always* made available via
> ExternalTypedData and any inner pointers into it are created via TypedDataViews.
>
> The embedder guarantees to the free kernel buffers it has provided to:
>     - Dart_CreateIsolateFromKernel
>     - Dart_LoadScriptFromKernel
>     - Dart_LoadLibraryFromKernel
>     - Dart_SetDartLibrarySourcesKernel
> on isolate shutdown.
>
> All other kernel buffers will get a finalizer attached, which ensures the
> kernel buffers get freed by the GC once they are no longer referenced:
>     - Kernel blobs for expression evaluation
>     - Kernel blobs for Hot-Reload
>     - Kernel blobs for cc tests
>

Liam Appelbe 3015d79371 [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.

Vyacheslav Egorov 969038934a [compiler] Fix EmitTestAndCall for a complete call of a Smi method. 
In rare circumstances we can generate a complete monomorphic
PolymorphicInstanceCall targeting a method of Smi class.

In this case we don't need to check anything - we can simply emit a
static call.

(This fixes a bug in the incorrect fix submitted earlier as
c67b9f2331 - even if call is complete
we still need to check for a smi receiver if there are more possible
receiver classes)

Fixes #37019
