This is the "next step" mentioned in
https://dart-review.googlesource.com/c/sdk/+/141240.
`List<UnresolvedType> typeArguments` were dropped (and null was passed)
in several cases in `handleSend`, but they are needed in
BodyBuilder.buildConstructorInvocation in the case where the receiver
of the constructor invocation is a type alias.
This CL ensures that the `typeArguments` are passed when needed, and a
named parameter `isTypeArgumentsInForest` is passed in order to preserve
the information about whether or not they have been to the `forest`.
The CL also adjusts tests '{generic_,}usage_type_variable_*' to fit the
decision made in language issue 848 that a type alias cannot be used
for constructor invocations when it (directly or indirectly) denotes
a type variable.

Updates Mar 19, for better precision in tests (that is, catching
more bugs):
Added tests where `r.m(null).isEven` is used
to near-verify that the receiver `r` implements `A<int*>`:
With `A<int>` it's an error to pass `null`, and with `A<int?>`
it is an error to invoke `isEven`.
Added '1_error' test to detect that `r.m(null).isEven` is a
compile-time error in cases where the receiver has a different
member signature for `m`.
Added '3_error' test to detect that it is a compile-time error to assign
'D().a' to a specific type, for many `D`. This helps catching the
situation where the member signature of `a` is legacy: if that were
true then this test will fail because there is no error).

Migrated language/bool tests expect TypeError when null value is used
in a condition (which is still possible if static type of condition is
dynamic). This is right in NNBD strong mode, as implicit cast of null
to bool will fail with TypeError. However, in NNBD weak mode implicit
cast passes, and then AssertionError is thrown as before.
Before migration language_2/bool tests expected AssertionError.
This change forks the tests to behave differently in weak and strong
modes.

error_stack_trace2_test: As part of the late field spec, we no longer
have a special error for cyclic statics, so they just end up with stack

Generalize `TypeAliasBuilder.unaliasDeclaration` such that it takes
an argument `typeArguments` and uses that to handle the case where
a type alias application ultimately expands to a type variable (e.g.,
with `typedef F<X> = X`, `F<int>` expands to `int`), and also to
emit a compile-time error in the case where such a type alias is
used to invoke a constructor or invoke/tear-off a static member.
Next step: Pass `List<UnresolvedType> typeArguments` from `handleSend`
to `finishSend` etc. to `BodyBuilder.buildConstructorInvocation`,
which seems to be a somewhat larger refactoring; needed in order to
make `generic_usage_class_test` pass. Some other fix is needed in
order to make `generic_usage_type_variable_test` pass.

- '_as' is now specialized on first use, like '_is'.
- '_is' specialization on `T?` that uses `T._is`
- recognize legacy versions of simple type tests (e.g. is int*)
The T? specialization makes a 2x improvement on some of the ListCopy
benchmarks on 'spec-mode' dart2js because some iterators have a T?
check.

One test verifies that the default values of fromEnvironment
constructors are the values false/0/''.
The other new test verifies that it is allowed to invoke an expression
whose static type is a proper subtype of a function type (X extends F,
where F is a function type), cf.

It seems that there's some fiddliness when writing error handling
lambdas in strong mode.
async_await_sync_completer_test: The lambda was implicitly trying to
return the result of a throw, which was Never. I've switched it to this
syntax, which implicitly returns Null instead.
stream_iterator_test: The error handler needs to return a Bool, for
compatibility with the Future.
I'm open to suggestions for cleaner fixes to these bugs.

A combination of `runZoned` and `runZonedGuarded` where only the latter allows an `onError` parameter,
and only that has a nullable return type.
Retains the `onError` parameter on `runZoned` for now because it's too breaking to remove it until packages have been migrated off of it.
It will be removed in a follow-up CL.

such that they do not depend on the default value, such that it
becomes a non-breaking change for code in the SDK repo to perform the
change in sdk and in sdk_nnbd.

Support Unix domain sockets communication on Linux, MacOS and Android.
Changes:
1. Add a field for InternetAddressType named unix.
2. Constructor of InternetAddress gains one more optional field: type. InternetAddress(String address, {InternetAddressType type});
3. Add another constructor to InternetAddress which taks raw address/path for ip/unix addresses as an argument. InternetAddress.fromRawAddress(Uint8List rawAddress, {InternetAddressType type});
The operation for unix domain sockets communication is basically the same as normal sockets except an InternetAddress with type unix should be passed.
