This CL replaces https://dart-review.googlesource.com/c/sdk/+/296900
The `List` constructor is removed in Dart 3.0.
Some of the `@patch` implementations were not removed.
This is *high priority*. It seems the left-over `@patch factory List` constructor did not cause any errors, instead it *added* a constructor to `List` that can be used in web compiled code. Even if `List` doesn't have such a constructor in the SDK code proper.
The VM and analyzer will say the invocation is an error, but dart2js happily compiles it and runs.
(It used to be that patches couldn't add public members, that security seems to have been removed.)
Also removes code which tries to detect "the unnamed List constructor",
which is no longer a thing, and a number of invocations of the constructor, where it's not clear that the test is aware that the constructor no longer exists, and is not marked as `@dart=2.x` with x < 12.

Previously, vectors of type arguments were expanded to include type
arguments corresponding to superclasses both in the instances of
generic classes and in Type objects (after type finalization).
As a result, Type objects after finalization could be recursive and
need to use extra TypeRef objects to break loops. The finalization of
types was very complex and sometimes slow.
This change simplifies the representation of Type objects: now they
always have short type argument vectors, corresponding only to
the type parameters of their own classes (both before and after
finalization). Vectors of type arguments in the instances of generic
classes are still expanded/flattened.
This greatly simplifies type finalization, makes Type objects
non-recursive and removes the need to create and handle excessive
TypeRefs for type arguments corresponding to superclasses,
as those type arguments are no longer included into types.
The only remaining use of TypeRefs is for bounds of type parameters.
In order to expand/flatten type arguments, new methods Type::GetInstanceTypeArguments / Class::GetInstanceTypeArguments
are introduced. They build canonical declaration type arguments
once (for each class), and then instantiate them as needed.
There are also simple helper methods to shrink type arguments (TypeArguments::FromInstanceTypeArguments) and expand type arguments without filling type arguments corresponding to superclasses (TypeArguments::ToInstantiatorTypeArguments).

TryCatchOptimizer pass reasonably expects for all MayThrow instructions
to have environment. AllocateSmallRecord instruction which is inserted
when boxing an unboxed record result of a call didn't have environment,
which caused crash in TryCatchOptimizer.
The fix is to copy the environment from a call instruction when
inserting AllocateSmallRecord.

Also adds `firstOrNull`, `lastOrNull`, `singleOrNull`, and `elementAtOrNull`.
I chose `nonNulls` instead of `whereNotNull()`.
The latter should have been a getter, but isn't.
Making it a getter in the platform libraries would be confusing,
and make migrating from `package:collection`'s function harder,
so instead I gave it a completely new name.
The alternative would be to retain the non-idiomatic `whereNotNull()`
for familiarity. But then it would be tool late to fix.

With the addition of records, it now makes sense to create an API
for parallelizing of futures of different types, like `Future.wait`
does for collections of same-typed futures.
The `wait` getters here apply to tuples of 2-9 futures of distinct types, which should be enough for most reasonable uses.
Planned addition for Dart 3.0.

Previously, a type with known cid was immediately selected, even
if another type also has a known cid. Now, if cids match, the static
types are also compared. This is useful for record types, because
static record type is more accurate than known kRecordCid.

There are currently users that implement classes (e.g. for mocking
purposes) that implement/extend NativeFieldWrappers and send such
objects across isolates.
This CL ensures such mocks can be sent across isolates again (which was
disabled in breaking change in [0]) as long as mocks do not extend NFW
(and therefore have actual native fields).
In the future the [NativeFieldWrapperClass]s will be marked as `base`
and therefore prevent implementing them, see issue [1].
=> At this point this CL can be reverted again.

Previously, when preparing a Parameter stub during inlining, compiler
unconditionally used argument type (from the caller). This type
could be less accurate than static or inferred parameter type of
the callee. For example, the argument could originate from inlined generic ListIterator.current:
v24 <- LoadField(v23 . _current@9040228) T{X0??}
and static type could be 'int'.
This change combines argument type from callee with a parameter type
from caller during inlining. In order to get parameter type for
optional parameters, ParameterInstr is extended to hold real parameter
index and ParameterIndex::ComputeType is extended to work on
parameters which are not passed directly.
Also, this change fixes the incorrect non-nullable receiver type for
Object and Null methods.

In Dart 3.0, bool is treated as an "always-exhaustive" type which means
it's a compile error to not exhaustively switch on it.
Since this is a regression test, I don't want to tweak the test and
risk not covering the regressed behavior, so pinning to 2.19 where this
wasn't a compile error.

Make intent explicit for classes which are intended as interfaces,
or which are not intended to be subclassed.
Mainly classes which are pure interfaces are marked as such,
and platform-specific classes not intended for subclassing
are made `final`.
The `final` classes includes `BigInt`, which is written to assume
that arguments inherit its private members
(it runs `_ensureSystemBigInt` on arguments).
It also includes the `Expando`, `WeakReference` and `Finalizer` classes,
which are just intended as stand-alone implementation classes for accessing
platform-specific functionality.

Original change's description:
> [vm] Remove tcmalloc and malloc profiler.
>
> The standalone VM originally began statically linking tcmalloc to work around bugs in the system malloc for Fiber. Later it used tcmalloc's hooks to implement a profiler, but this is rarely used since it is only available in debug mode, misses early allocations, and often misses late allocations from an exhausted sample buffer. Removing it altogether avoids build complexity around which combinations of compiler/architecture/sysroot support tcmalloc, and reduces binary size.

First, canonicalized CharacterRanges allow for QuickCheck code to be generated, rather than skipped. Second, CharacterRanges could become canonicalized later leading to incompatible instructions generated on a second compilation run, leading to a crash.

Without sound null safety result of int.parse is inferred as nullable,
making the IL test vm/dart/records_allocation_sinking_il_test dependent on
the sound null safety mode.
The test is changed so the argument 'x' of 'test' is always non-nullable
and always unboxed.

This is follow up to 65f4a733bb,
which switched optimized code to use fixed frame for outgoing
arguments.
Change Kernel to IL translation to handle null-checks in
invocations differently: this code used to duplicate receiver on
the stack to accomodate for PushArgument in unoptimized code, but
PushArgument has not been inserted since f4e61eacfd,
which means duplication of the receiver is no longer necessary.
