Jens Johansen 1f9d59c807 [CFE] More dart scope calculator stuff
General approach: Find all scopes for an offset,
then pick "the right one".

This still leaves a few offsets where we can't pick 1 scope in the
(non-outline) dills in the out directory though.

More thorough testing will follow.

Daco Harkes 1755f89092 [vm/ffi] Add class modifiers
Adds class modifiers to `dart:ffi`.

Migrates all user-defined subclasses of `Struct`, `Union`, `Opaque`,
and `AbiSpecificInteger` to be `final class`es.

Does not remove the manual error checking, so some errors will show up
twice now in language version 3.0. In language version <3.0, only the
FFI-specific error will show up.

In a follow-up CL, we will try to make the language-errors to show up
also <3.0 so that we can remove the FFI-specific errors.

Examples of duplicated errors:

Aske Simon Christensen c2339ee782 [dart2wasm] Basic FFI support
Implements memory access through the `Pointer`, `Struct` and `Union` FFI
types. `Pointer` supports `fromAddress`, `address`, `elementAt`, `cast`,
`value`, `ref` (only getter), `[]`, `[]=` (not for structs and unions),
`==` and `hashCode`. Structs and unions support getters and setters for
their members.

`Pointer`, `Struct` and `Union` are all represented as `i32`, both
internally and in imports and exports. They currently don't have any
boxed representation, which means they can't be nullable (a `Pointer`
can still contain `nullptr` - the C null) and can't be assigned to
supertypes (i.e. `Object`, `dynamic`, type variables), stored in
containers nor passed as arguments or return values of local functions
or function expressions. To pass an FFI value in these situations, box
it manually by storing it in a field.

For the FFI integer types, only the explicitly sized versions (e.g.
`Int8`, `Uint32`) are supported.

Whenever the feature is used, the module will import a memory by the
name "ffi.memory", which will be accessed by the operations.

This also adds an optional commandline argument to `run_wasm.js` to
specify the module containing the FFI code. When such a module is
specified, it will be instantiated first, and its exports will appear as
imports to the Dart module under the "ffi" module name.

Daco Harkes 3156c5629d [cfe/ffi] Implement Finalizable
This CL implements `Finalizable` by means of a CFE transform.
The transform is implemented in the existing FFI transform to avoid the
overhead of traversing the AST an extra time. The FFI transform slows
down ~15-30% on Flutter Gallery. For more info see the design doc.

Daco Harkes 045b9c1715 Reland "[vm/ffi] Add common C types"
We're adding these types to `dart:ffi` rather than `package:ffi` so that
they can be used with `FfiNative`s.

Adds `NativeType`s for the following C types:

* unsigned char
* signed char
* short
* unsigned short
* int
* unsigned int
* long
* unsigned long
* long long
* unsigned long long
* uintptr_t
* size_t
* wchar_t

Because the C standard only defines minimum sizes for many of these
types, future platforms might diverge from the typical size even if all
platforms currently agree on a size. To avoid having to reification
later, we define all types as AbiSpecificIntegers rather than typedefs,
even if all current target platforms agree on the size.

Closes: https://github.com/dart-lang/sdk/issues/36140

Daco Harkes acdf82de17 [vm/ffi] ABI-specific integers
This CL adds support for users defining integers which are mapped to
differing sizes and signedness based on the application binary interface
the Dart VM is running on.

Notable implementation design decisions:
- ABIs are open world, so that adding an ABI to the Dart VM does not
  break existing definitions. Thus, we only figure out in the VM that
  we're missing a mapping. We throw compile-time errors.
  - In AOT, these show up in the precompilation step.
  - In JIT, these show up as `_CompileTimeError` at runtime. Note that
    these can be caught. So in subsequent compilation steps we need to
    ensure that we also throw the same compile-time error.
- We match on the call-sites (streaming_flowgraph_builder) rather than
  method bodies (kernel_to_il) of AbiSpecific loads and stores so that
  we can compile for the int-size of the call site.

Jens Johansen ed802c248d [CFE] Fix constant coverage for super calls
Previously super calls used the constructer they we're super's for as
callers when accounting for coverage. That's not accurate (in that it's
not the cause for the evaluation) and is fixed here.

Simon Binder be893fdf27 [vm/ffi] Add providesSymbol to DynamicLibrary
This adds the providesSymbol method to DynamicLibrary. It returns
whether the library contains a function with the given name.

As per dlsym(3), it is valid for dlsym to return nullptr in a success
case if the symbol actually has a NULL value. So I've changed the logic
to check for dlerror() after we invoke dlsym(), both in the existing
lookup and in the new method.

Closes https://github.com/dart-lang/sdk/issues/46192

Daco Harkes 4ba4fd3f1d [analyzer/ffi] Inline array annotation const dimensions
Moves the Array forwarding constructors and _ArraySize class out of
the patch files so that the analyzer can reason about them.
(The analyzer does not include patch files, because it does not know
whether it's analyzing for VM or JS backend.)

Daco Harkes ffa5d16ae7 [vm/ffi] Support multi-dimensional inline arrays
This CL only changes dart:ffi API, CFE, and analyzer. No VM changes
were needed because the dimensions of inline arrays can be flattened
before passing them to the VM. The multi-dimensionality does not
impact the ABI.

Daco Harkes 0295dfc74e [vm] Support redirecting external const factories
This CL introduces the first combination of `external const factory`
with `@patch const factory (.*) = (.*)`. This specific combination was
never used in the core libraries, and did not work.

Half of the fix is a missing flag from the CFE:
https://dart-review.googlesource.com/c/sdk/+/187440

The other half of the fix is matching on the
kRedirectingFactoryConstructor tag, and allowing constructor names
in procedure targets (even though we never compile those expressions
because they are invalid).

Bug: https://github.com/dart-lang/sdk/issues/45101

TEST=Using redirecting const factory in patch file in core lib.

Daco Harkes d45fd0f9d5 [vm/ffi] Support inline arrays in Structs
Adds support for single dimension inline arrays in structs. Multi-
dimensional arrays will be supported in a future CL.

This CL adds:
- CFE static error checks for inline arrays.
- CFE transformations for inline arrays.
- VM consumption of inline array fields for NativeType.
- Test generator support for inline arrays + generated tests.

Previous CLs added support for inline arrays in:
- analyzer https://dart-review.googlesource.com/c/sdk/+/183684
  - updated in this CL to new API.
- ABI calculation https://dart-review.googlesource.com/c/sdk/+/183682

Closes: https://github.com/dart-lang/sdk/issues/35763

Open issue: https://github.com/dart-lang/sdk/issues/45101

CFE transformations are tested with expectation files:
TEST=pkg/front_end/testcases/(.*)/ffi_struct_inline_array.dart

Trampolines and CArray API are tested with end-to-end Dart tests:
TEST=tests/ffi(_2)/(.*)by_value(.*)test.dart
TEST=tests/ffi(_2)/inline_array_test.dart

Compile-time errors (both CFE and analyzer) are tested in:
TEST=tests/ffi(_2)/vmspecific_static_checks_test.dart
