Fixes#27505
This relands fc775b3e9b with a fix to
VirtualMemory::~VirtualMemory: on Windows the only way to release
virtual address mapping is to invoke VirtualFree(..., MEM_RELEASE) with the
original base pointer returned by VirtualAlloc - that is why we need to call
VirtualFree is size of the reservation is 0: the whole reservation might have
been decommitted by VirtualFree(MEM_DECOMMIT) but it is still present.

While generating bytecode, avoid flattening of type arguments used for
instance allocations (and thus avoid creating new types when substituting
type parameters). This is a workaround to limitation of kernel metadata
which is unable to serialize references to nodes (such as DartType)
not reachable from root Component.

It's not generally safe to continue to use the Shadow nodes after they
have had their type inferred, because they give a false picture of the
tree. In this case it led to an assertion failure.
Move the assert to a place in the code where it is true. Use the
correct subexpression for subsequent check insertion. Clear the
parent pointer when Kernel nodes are removed from the tree to try to
catch problems like this.

This makes the Flutter repo analysis about 6% faster.
Before: 56.9 57.4 56.9 57.3 56.5 56.9 56.6
After: 53.5 53.0 53.8 54.3 53.5 53.0 53.0
To see the different better, I ran lints 100 and 10 times for each file.
Before: 628 621 109 107 109
After: 338 333 77 75 76
To get these numbers we will need to make corresponding changes to lints,
to implement these interfaces, so that they are used instead or the
current visitors. I have these changes locally, but we would need to
publish analyzer first.

This reduces small tagged integers on 64 bit platforms from 63 bits to
31 bits plus one tag bit.
This is a step on the way to compile-time-optional compressed pointers
on 64 bit platforms. See more about this at go/dartvmlearnings
This causes a slowdown for some uses of integers that don't fit in 31
signed bits, but because both x64 and ARM64 have unboxed 64 bit
integers now the performance hit should not be too bad.
This is a reapplication of
https://dart-review.googlesource.com/c/sdk/+/46244
It was reverted due to a compilation error on 32 bit
ARM with DBC.

- Drop the `copy_observatory` and pub get steps. Use a checked in
`dart2js.packages` file and build from the source tree.
- Invoke dart2js directly for the build command.
- Use the dart2js executable checked in to the SDK when it is available,
otherwise fall back on the dart VM and dart2js source.
- Manually synthesize a filered `packages` directory out of the source
directories for observatory and it's dependencies
- Remove transformer section of the pubspec since it's unused.

Allows a rule to depend on create_sdk and declare a part of the SDK as an input. Doing both is good style in GN, and is needed for polymorphism with a prebuilt SDK, which would have an empty dependency and an input to detect updates to the prebuilt artifacts.

Implements a new strategy for closed world computation that takes
the static type of the receiver into account when processing dynamic
calls.
For this to work, the J-model needs to only contain live members,
meaning queries can no longer assume that a J-model member exists for
instance for JSString.split because it might not be live.
This is the initial implementation which only uses
ir.MethodInvocation.invocationTarget. Later we will use the static
type of the expression on ir.MethodInvocation, ir.PropertyGet, and
ir.PropertySet.
