The bad arity maybe detected after an isolate reload or when using strong mode with a mix of opted in and opted out libraries.
The thrown NoSuchMethodError contains enough information to be useful, but does not mirror the complete invocation (e.g. arguments).
This CL does not fix https://github.com/dart-lang/sdk/issues/37517 where the target is missing after a reload (not just bad arity).
The VM implementation of NoSuchMethodError is cleaned up, but the deprecated constructor 'NoSuchMethodError(...)' is not yet removed, since it is still documented.

IsTopTypeForAssignability is renamed to IsTopTypeForSubtyping to better
reflect that it works both for subtyping and assignability.
Most uses of IsTopType() are changed to IsTopTypeForSubtyping().
The remaining uses of IsTopType() are checking for top types in
instance-of ('is') tests, so IsTopType is renamed to IsTopTypeForInstanceOf.
Also, Instance::IsFutureOrInstanceOf is renamed to RuntimeTypeIsSubtypeOfFutureOr
to align it with RuntimeTypeIsSubtypeOf and reflect that it is
calculating subtyping and not instance-of.

Using strong mode with a mix of opted in and opted out libraries may result in a static call with bad arguments (missing required named argument) that may crash the VM with an assert fault. Ideally, we should emit code to throw a NoSuchMethodError when the code is executed. For now, we report the error as an informative exception during compilation instead of aborting.
The name of the enclosing function needs to be canonical when creating an instance of _FallThroughError when compiling a switch statement.

Introduces NativeRepresentation and NativeLocation for the compilation of FFI.
NativeRepresentations are able to express all representations (or types) of the native ABIs we bind to with FFI, this is more representations that than that are used in Dart itself.
NativeLocations are able to express all locations of the native ABIs we bind to with FFI, this is more types of locations than that are used for the Dart calling convention.
See the documentation in the respective files.
These NativeLocations and NativeRepresentations are computed by the NativeCallingConvention and consumed by the Marshaller and Assemblers.
This reenginering is required for go/dart-ffi-by-value, hardfp (Arm S and D fpu registers), and iOS 64 bit (non-word-aligned stack arguments).
In addition, by using the NativeRepresentations we also get slightly reduced code size:
* The tracking of sizes is improved, so less sign/zero-extension operations are required.
* UnboxedWidthExtenderInstr is fully removed, the size extension is done inside the native moves, coalescing moves and size extension when possible.
* BitCastInstr is only used when really needed. This reduces code-size on arm32 softfp.
This fixes the iOS arm64 calling convention, manually tested with https://github.com/flutter/flutter/pull/46078 and https://dart-review.googlesource.com/c/sdk/+/131074.

* Fixes a crash in dartkb mode, when the function of the Bytecode

* Does a simple integration of the lazy async stacks in debugger.cc -

Flutter Gallery ARMv8: -0.8% total, -1.3% instructions
Flutter Gallery ARMv7: -0.7% total, -1.2% instructions
There are some performance regressions, in four categories:
1. Arithmetic on num types (e.g. MinLib, MaxLib):
We believe arithmetic on num types is rare in practice, and can be optimized later
by specializing the call-sites.
2. Lack of types (e.g. MeshDecompression, ImagingGaussianBlur, Crypto*):
These (and similar benchmarks) are written in a very untyped style, which is not
representative of Dart 2 style. We've confirmed that the regressions disappear if
the benchmarks are annotated with appropriate types.
3. Megamorphic calls which are specialized in the benchmark (e.g. DeltaBlue):
DeltaBlue uses string interpolation in one place, so the toString() method in the
string interpolation helper is monomorphic for _Smis. However, in a realistic programs,
string interpolation is used much more frequently and with different types, so it's very
unlikely that this call would be monomorphic. When string interpolation is removed, there's
a remaining 1.3% regression on DeltaBlue which is not yet accounted for.
4. Noisy benchmarks
The remaining regressions are on benchmarks which show frequent jitter historically.
There are also 1-4% improvements on many benchmarks (Golem's "noise" analysis is hiding
many of them, look at the graphs).
For the reasons above, we believe the regressions justified by the code size improvement.

nnbd semantics although run in weak mode.
