These fences were added before we decided that (1) `NativeFinalizer`s
are only attached to `Finalizable`s and (2) `Finalizer`s do not have
a guarantee against premature finalization.
Now that we're inlining, we should avoid allocating the `Pointer`

This change fixes the following 2 bugs related to unwinding records
on Windows:
1) When cross-compiling from another OS to Windows, unwinding records
were not added to the end of the code section. Later, when loading
AOT snapshot, arbitrary bytes at the end of the code section were
used as the unwinding data, which could result in the errors
returned from Windows API calls.
2) When code section is mapped, its size was rounded up to the page
size; when looking for unwinding record, size of the unwinding
record was subtracted from the rounded size. This is not correct
as unwinding record is placed right at the end of code section,
so code section size should be used before rounding.
Also, magic value is added to the unwinding record in order to
verify that it is preserved and correctly found.

Since we already cache instantiation of type argument vectors to avoid
runtime calls as long as the cache has room, remove the default
type arguments field from Closure objects. Instead, just perform any
needed instantiation when the default type arguments are needed
using the instantiator and parent function type arguments stored
in the closure.
Also rename DefaultTypeArgumentsKind to InstantiationMode and
generalize the calculations to determine how to instantiate default
type arguments to an operation that can be performed on type arguments
in general.

The refactoring in https://dart-review.googlesource.com/c/sdk/+/345002
erroneously assumed that if the caller to
Assembler::AddressCanHoldConstantIndex didn't pass an out parameter to
detect whether a base register was needed, that that case shouldn't be
considered.
While it's true that LoadIndexedInstr::MakeLocationSummary originally
ignored the value stored in the out parameter, it did that because it
can use TMP to store the array base, unlike the code for
StoreIndexedInstr which must have a temporary register allocated during
register allocation.
Thus, fix Assembler::AddressCanHoldConstantIndex to always require
the out parameter, and add a comment in LoadIndexedInstr as to why
we ignore the out parameter in this case instead of allocating an
additional temporary register.

Previously, they were implemented as native methods with special
replacements in the inliner.
Instead, create force-compiled versions of the original inliner
replacements and use those instead of native methods, unless the
flow graph compiler doesn't support unboxing the requested element type.
In that case, the force-compiled version just calls a native method,
and we only keep the native methods that might be needed (that is,
for double/SIMD element access).
Also, revert the change in 26911a6176, since now the _getX/_setX
methods are appropriately inlined instead of failing to inline due
to being native methods.

Previously, CanBeImmediateIndex calculated the scaling factor for the
index using Instance::ElementSizeFor. However, the LoadIndexed and
StoreIndexed instructions which use this function have an index_scale_
field that is not necessarily the same as the element size for the
class id. This means the displacement calculated within
CanBeImmediateIndex can differ from the actual displacement calculated
within ElementAddressForIntIndex, causing the bug seen by the fuzzer.
This CL moves the check in CanBeImmediateIndex to a new static
method Assembler::AddressCanHoldConstantIndex. In addition to the
original arguments to CanBeImmediateIndex, the new static method takes
an index_scale argument, so the field value can be passed appropriately.
It also adds an is_external argument on X64 and IA32 to match the other
architectures, since assuming a non-external typed data object could
cause a register to be used in cases where it isn't necessary.

Previously, the default type arguments for closure functions were
instantiated in the same way as other types of functions, where the
instantiator and function type arguments of the call were used. However,
the defaults for closure functions should be instantiated with the
instantiator and parent function type arguments stored within the
closure itself.
Since the instantiation of the default type arguments only depends on
the instantiator and parent function type arguments, which are shared
between partial instantiations of the same generic closure, the VM
performs this instantiation once at closure creation and caches it in
the closure object, so it can be retrieved when the default type
arguments are needed and copied to new partial instantiations of the
same closure without need for recalculation.
As a side effect, this should speed up dynamic invocation of generic
closures, since the invoke field dispatcher that implements them
previously performed this instantiation when needed on every invocation,
but now it just retrieves the cached version instead.

If a static field or getter is annotated with

to true, then uses of the static field or getter are const evaluated
when a target operating system is available. If <cond> const evaluates
to any other value, then the annotation is ignored.
For example, when runtime-only code is guarded like the following,
using Flutter's kDebugMode constant, then debug mode Flutter programs
can alter the defaultTargetPlatform for testing, but in release mode,
the defaultTargetPlatform getter is const evaluated and code guarded
with defaultTargetPlatform checks can be eliminated if unreachable:
