This CL replaces `late Finalizable` variables with the original and
a nullable non-late variable. Every assignment is done first to the
late variable, and the immediately to the nullable non-late shadow
variable. The reachability fences are then inserted only for the
nullable non-late shadow variable.
The advantage of this is that the semantics are fully valid and none
of the further compiler pipeline has to know about late Finalizables.
(1) We remove the special casing in the VM.
(2) The TFA logic with finalizables is no longer blocked.
The downside of this approach is that we use more memory, we need
two fields at runtime, one storing a null and the other storing a
sentinel on initiazation. Moreover, we get some extra store
instructions.

This improves the support for logical and pattern by making an
approximation of the intersection of spaces. When creating an
intersection between two [SingleSpace]s, if one of the static
types is a subtype of the other, this used for the create
intersection. Otherwise the intersection is modelled by including
an "unknown space" in the result.

This changes the Space computation for CastPattern to just the
Space for the subpattern. For a non-throwing cast, this is exactly
what the pattern will match.
There is still potential for handling the types rejected by the cast.
For instance recognizing that the (yet) unhandled subtypes of a
sealed type are exhausted by the throw.

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.

This proved to be quite a bit more time consuming than I'd realized,
and it was a lot harder to verify the results than I would have
guessed.
But I think it made it easier to see holes in our location coverage
to have the tests split up this way. I decided not to fill those
holes in this CL in the hope that it's easier to see the
correspondence between the old tests and the new tests.

Changes:
- Instantiation context structs now have a common supertype:
`#InstantiationClosureContextBase`. This supertype is used to check if
a closure is an instantiation.
- Generic closure vtables now have one more entry for comparing types in
instantiation contexts.
- All instantiations with same number of types use the same context
struct type and the vtable entry for comparing types in contexts.
- `_Closure._equals` checks if closures are instantiations (with a type
test against `#InstantiationClosureContextBase`), and if they are,
gets the contexts and calls the function in the vtable for comparing
the types in the contexts.

We've changed const `==` to be based on primitive equality. It used to
just be an allowed list of concrete types, but now `==` is a valid
constant expression on any type that has primitive equality.
This change isn't directly part of patterns, but is enabled under the
same flag.
Update this test to the new semantics.

Querying the thread clock takes the overwhelming majority of time when using the VM-internal recorders (ring, startup, endless, file). Including the thread clocks in the timeline allowed visualizing roughly how much an event got scheduled out, but not when. This is a high price to pay for such fuzzy information. Precise scheduling information is available from Fuchsia tracing, systrace or Signposts.
```
import "dart:developer";
main() {
var n = 1000000;
var watch = new Stopwatch()..start();
for (var i = 0; i < n; i++) {
Timeline.timeSync("EventName", () {});
}
print("${watch.elapsedMicroseconds.toDouble() / n} us/event");
}
```
--timeline_recorder=ring 2.751822 -> 0.487936 us/event (5.64x)
--timeline_recorder=systrace 0.440439 -> 0.435997 us/event

This contains support for all of the 3.0 language features. It also
contains a couple of very minor style changes. Unlike the previous
reverted roll (https://dart-review.googlesource.com/c/sdk/+/285460),
this does *not* contain the style change to support compact switch
statements. This should eliminate most of the style churn.
