Ryan Macnak b1c09ecd8f [vm] Make naming more consistent when converting between handles, tagged and untagged pointers.
Currently we have things called XPtr which are not what you get from ptr().

Old world:
handle->raw() returns RawObject* (tagged)
raw_obj->ptr() returns RawObject* (untagged)

After 6fe15f6df9:
handle->raw() returns ObjectPtr
obj_ptr->ptr() returns ObjectLayout*

New world:
handle->ptr() returns ObjectPtr
obj_ptr->untag() returns UntaggedObject*

Regis Crelier b3bca1821c [VM/runtime] Decouple representation of function signatures from Function objects.
This fixes issue https://github.com/dart-lang/sdk/issues/43088

This CL improves on https://dart-review.googlesource.com/c/sdk/+/166920 by keeping the names of type parameters.

Victor Lima b951498903 [vm/aot] Allow static methods to have unboxed args and return
Static methods and constructors may receive unboxed parameters.
This change adds a bitmap to the RawFunction object indicating
which parameters are unboxed and their types. Also, the stack frame
bitmap was updated to include new bits for those parameters.

The ArgumentsDescriptor object was updated to store not only the number
of arguments, but also their size, since 32-bit platforms would use two
words for each int64 and double value.

In addition, static methods that return non-nullable integers
and doubles may return these values unboxed.

Florian Schneider 8d38a58c18 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.

fschneider@google.com cd54507fc2 Mark native functions when they are created.
Until now the parser marked native functions as native when parsing.

This may be too late for some functions. E.g. the native typed list
constructor may not be invoked because the intrinsic code is executed
instead (unless for example new-space allocation fails).

This causes missing type information when optimizing functions using
those recognized factory functions like Uint8List._new.

asiva@google.com ec7f44f025 Create frequently used symbols in the vm isolate
- Avoids the need for doing a NewSymbol on these everytime
- saves space as they get shared by isolates

asiva@google.com 73bfbc5da4 Allow implicit 'close your eyes' of native methods. This will hopefully fix issue 3466.
- when resolving the native method which has been closurized account for the 'this' argument in the count of arguments.
- explicitly copy the 'this' parameter in the closure context as the first parameter before calling the native function. This is done by piggy backing on the CopyParameters code used for functions with optional parameters.

srdjan@google.com a54f33bf92 ICData is now a wrapper object that refers to the calling function, target name, ic data array, etc. The old ICData C++ class that wrapped around an Array is removed. The advantage is that the ICData object remains the same, only its ic_data array object is being modified as classes are added..
TODO: store ICData-s into function so that the type feedback can be easily extracted (currently must traverse the unoptimized code).
