Zichang Guo b8a6e77700 Update operatingSystemVersion on MacOS/iOS to return system version instead of kernel version
Platform.operatingSystemVersion on MacOS/iOS returns the version of the
kernel. It should instead returns system version.

This cl will try to use recently added "kern.osproductversion" to get
the system version. If it failed, try to read from "SystemVersion.plist".
Falls back to original kernal version if none of them succeed.

Zichang Guo 42fcc18fcc Reland "File::Copy avoids direct copying on Windows"
This is a reland of 391d3bcdd8

The root cause of the failure is that the destination path uses forward
slashes as path separator.

This fix checks for forward slashes as a potential path separators.
If both forward and back slashes exist, the one closer to the end of the
path will be used to get the destination directory.

If any step fails, it will fall back to original copy.

> File::Copy avoids direct copying on Windows

> There is a race condition for copying file on Windows, where CopyFile()
> returns success but data has not been populated into destination file.

Clement Skau 0ce83987d6 Reland "[SDK] Adds an SDK hash to kernels and the VM."
Note: This is a reland of https://dart-review.googlesource.com/c/sdk/+/150343

Adds a new SDK hash to kernels and the VM which is optionally checked
to verify kernels are built for the same SDK as the VM.
This helps catch incompatibilities that are currently causing
subtle bugs and (not so subtle) crashes.

The SDK hash is encoded in kernels as a new field in components.
The hash is derived from the 10 byte git short hash.

This new check can be disabled via:
  tools/gn.py ... --no-verify-sdk-hash

This CL bumps the min. (and max.) supported kernel format version,
making the VM backwards incompatible from this point back.

This also bumps the min. and current ABI version.

Tess Strickland 9329995dd8 [vm] Add a separate invoke field dispatcher for dynamic closure calls.
Adds TODO comments in appropriate places for future work that will move
non-covariant type checks out of the closure body. Instead, the VM will
perform them in the invoke field dispatcher (or NoSuchMethodFromCallStub
if --no-lazy-dispatchers is used) when a dynamic call is detected.

This change has minimal negative effects on the code size. Here are the
code size change percentages for the Flutter Gallery in release mode:

Alexander Markov 06a8cc8dea [vm/nnbd] Use separate runtime entry for throwing _CastError in null check operator
Previously, NullError runtime entry was used both to throw
NoSuchMethodError and _CastError. _CastError was used if selector is
null. However, with --dwarf-stack-traces CodeSourceMap is not preserved
and selector is not available, so wrong exception type was thrown.

This is fixed by introducing separate NullCastError runtime entry along
with corresponding shared stubs.

NullErrorSlowPath is extended to support 3 exception types
(NoSuchMethodError, ArgumentError and CastError).
NullArgErrorSlowPath is removed as it duplicates NullErrorSlowPath.

Vyacheslav Egorov 49d733ebc3 [vm/aot] Fix handling of dynamic calls through getters
When discovering getters which might be potentially hit by a dynamic
call through a getter we need to ignore method extractors.

DispatchTableGenerator eagerly creates some of the method extractors
and these extractors were accidentally pulled in by
CheckForNewDynamicFunctions(): if there is an dynamic invocation
of `foo` in the program we would compile all getters `get:foo` 
because `x.foo()` might be a dynamic call-through-getter `x.foo.call()`.

However this logic should not apply to method extractors because
`x.foo(...)` would never hit an extractor for `foo`, it would
hit method `foo` itself.

Removes 15K (0.04%) of total uncompressed code size on a large 
internal application.

Clement Skau edde575dcd [SDK] Adds an SDK hash to kernels and the VM.
Adds a new SDK hash to kernels and the VM which is optionally checked
to verify kernels are built for the same SDK as the VM.
This helps catch incompatibilities that are currently causing
subtle bugs and (not so subtle) crashes.

The SDK hash is encoded in kernels as a new field in components.
The hash is derived from the 10 byte git short hash.

This new check can be disabled via:
  tools/gn.py ... --no-verify-sdk-hash

This CL bumps the min. (and max.) supported kernel format version,
making the VM backwards incompatible from this point back.

Daco Harkes da39a4abff [vm/ffi] Remove try-catch from ffi trampoline if no handle scope
https://dart-review.googlesource.com/c/sdk/+/145591 introduced a try
catch into FFI calls to call ExitHandleScope on the exception path.
However, we only need this try-catch if we actually need to exit the
handle scope on the exception path, which is not the case if we have
no handles in the signature. So this CL makes the try catch optional.

This speeds up ffi calls without handles (tested on JIT x64):
FfiCall.Uint8x01(RunTime): 206.4801280066068 us.
->
FfiCall.Uint8x01(RunTime): 203.7240782236708 us.

Also adds a test that checks that an exception can still be propagated
with Dart_PropagateError from native code when the FFI trampoline has
no try catch.

David Morgan 6bdf55f31f Revert "[vm, service, observatory] Bang Bang (My Type System Shot Me Down)."
This reverts commit 65e3c9d3b1.

Reason for revert: package:logging, package:stack_trace and package:usage need to be migrated first.

Original change's description:
> [vm, service, observatory] Bang Bang (My Type System Shot Me Down).
> 
> Port the service tests and Observatory to Dart 3.
> 
> Changes from the original landing:
> 
>  - The old tests are copied to observatory_2 / service_2 so the service can still be tested when running a legacy mode program
>  - The test harness is taught about 'service_2'
>  - Observatory's package is added to front end's opt-in list
>  - Fixed some places in the bot configuration matrix so ensure 'service' runs on legacy bots and 'service_2' on weak-mode bots
> 
> The ported tests themselves are not changed.
