It was pointed out that the previous fix
(5c74e0e16f) wasn't strong mode safe
because the returned array when length = 0 was not properly typed.
This fixes the issue by removing the old fix and simply removing the
assert.

There's an assert in InvocationMirror_unpackTypeArguments checking that
the length of the incomming TypeArguments is positive (len > 0).
That's not a valid assert.
When creating TypeArguments it will be TypeArguments::null() if it is
empty or contains only dynamic.
TypeArguments::null() will answer 0 as length which is thus perfectly
valid.
This CL fixes the wrong assert (technically it returns before the assert,
but still).
Fixes#31381.

* double.compareTo(int) is fixed to handle integers which are not
precisely representable as doubles.
* int.compareTo(double) is fixed to properly handle doubles which
are clamped when converted to integers (with Dart 2.0 fixed-size
integers).
* Test for num.compareTo is updated for fixed-size integers; more corner
cases added.

Update status files.
This cl includes implementing these two features on all platforms:
1) Support calling generic functions via DartEntry::InvokeFunction().
2) Support native generic functions. These are currently allowed, but type
arguments are ignored, and therefore not accessible from the C++ side.

The only fix needed for relanding is adding _ensureScheduleImmediate
to the list of vm entrypoints in //runtime/vm/compiler/aot/precompiler.cc
Original commit message:
Adds a top-level call waitForEventSync to dart:io that blocks the
thread an Isolate is running on until messages are available.
Before the thread blocks, the microtask queue is drained.
Before waitForEventSync returns, all messages are handled.
Lifting this up from a comment:
This is apropos of the request that nweiz@ sent to the mailing list a
couple weeks back. I'm not sure we should land this. We certainly
shouldn't land it without some annotations that will make the analyzer
complain a lot in most configurations, but I don't know what those
annotations are.

Without strong mode, a "good enough" implementation is to simply call
the generic method with "dynamic" for the type arguments, which is what
this does. That should be enough to unblock our internal users.
We also need to not report a compile error when
dart_internal/extract_type_arguments.dart imports the hidden
"dart:_internal" library.
This patch does both of those for the VM and dart2js (using its old
front end).
Note that the test still fails because the test is more particular than
most actual user code would be -- it validates that the instantiated
type arguments are *exactly* correct, and not that the returned object
is merely subtype compatible.

The informal spec for strong mode top level inference
(https://github.com/dart-lang/sdk/pull/28218) says "If there are
multiple overridden/implemented methods, and any two of them have
non-equal types (declared or inferred) for a parameter position which
is being inferred for the overriding method, it is an error."
This CL fixes several SDK errors that arise from this rule. For
example, the classes _Closure, Function, and Object contained members
declared as follows:
class _Closure implements Function {
bool operator ==(other) ...
}
class Function {
bool operator ==(Object other) ...
}
class Object {
bool operator ==(other) ...
}
The type of Object's operator == was (dynamic) -> bool; the type of
Function's operator == was (Object) -> bool; therefore the type of
_Closure's operator == (which overrides both, since _Closure extends
Object and implements Function) cannot be inferred and must be
specified.
A similar situation exists for _Double and _IntegerImplementation
(both implement num, which declares operator == to have type (Object)
-> bool), and _Uri (which implements Uri, which declares operator ==
to have type (Object) -> bool).
This CL fixes the error by specifying the type explicitly in the
classes _Closure, _Double, _IntegerImplementation, and _Uri.

There is no actual implementation here yet (that's your job :) ), but there is:
- An external method in dart:_internal, extractTypeArguments().
- Empty patch methods for that for the VM, dart2js, and DDC. These need to have implementations
filled in.
- A "dart_internal" package to expose a subset of the API. It gives you:
extractListTypeArgument()
extractMapTypeArguments()
We'll bring this into Google, but not publish it externally unless we find we really need to.
- A test for the behavior. It probably has bugs since I can't run it.

This allows us to avoid going into runtime even if strong mode is
enabled: type checking is handled in the []= operator itself and
_setIndexed does not need to check types and thus can be intrinsified.
This CL also removes inline type checking done in ia32 version,
not other platform had it.

This is a strong mode migration that was missed in the earlier rounds.
It allows use of functions that have a more restricted argument type than Object in strong mode
while still ensuring that the argument has a correct type.

This reverts commit f13f772bb2.
Reason for revert: dartk(p)-strong debug mode is completely broken
because we convert int values non-representable as Smi to Smi, which
triggers that assert. The code that does tagging checks that
Untag(Tag(x)) == x, however for our purposes this identity does not
need to hold because we only care about lower bits and ignore the sign.
Reverting to restore green-ness of DEBUG builds.

"If" tests like `if (entryPoint is _BinaryFunction)` are too general;
they only guarantee that `entryPoint` accepts arguments of type
`Null`, whereas in practice `entryPoint` accepts other values. Once
runtime check insertion is complete, this will cause the front end to
insert implicit downcasts at the time of the call to `entryPoint` to
cast the parameters to `Null`.
Suppress these casts by casting `entryPoint` to `dynamic` at the time
of the call.
