- Refactor the ValueSerializer tests using raw data, so that we test all
valid versions for each test (not only one hard-coded one)
- Mark some tests as backwards compatibility tests, to make it less
likely that somebody updates them not realizing they are backwards

These tests cover the basic VirtualAddressSpace functionality for the
three different types of address spaces currently available: the root
space, subspaces, and emulated subspaces.
This CL also includes minor bugfixes in VirtualAddressSpace
implementations and removes RandomizedVirtualAlloc in platform-win32.cc
which doesn't seem to do anything useful anymore but prevents page
allocation hints from working correctly.

This CL renames a number of things related to the V8 sandbox.
Mainly, what used to be under V8_HEAP_SANDBOX is now under
V8_SANDBOXED_EXTERNAL_POINTERS, while the previous V8 VirtualMemoryCage
is now simply the V8 Sandbox:
V8_VIRTUAL_MEMORY_CAGE => V8_SANDBOX
V8_HEAP_SANDBOX => V8_SANDBOXED_EXTERNAL_POINTERS
V8_CAGED_POINTERS => V8_SANDBOXED_POINTERS
V8VirtualMemoryCage => Sandbox
CagedPointer => SandboxedPointer
fake cage => partially reserved sandbox
src/security => src/sandbox
This naming scheme should simplify things: the sandbox is now the large
region of virtual address space inside which V8 mainly operates and
which should be considered untrusted. Mechanisms like sandboxed pointers
are then used to attempt to prevent escapes from the sandbox (i.e.
corruption of memory outside of it). Furthermore, the new naming scheme
avoids the confusion with the various other "cages" in V8, in
particular, the VirtualMemoryCage class, by dropping that name entirely.
Future sandbox features are developed under their own V8_SANDBOX_X flag,
and will, once final, be merged into V8_SANDBOX. Current future features
are sandboxed external pointers (using the external pointer table), and
sandboxed pointers (pointers guaranteed to point into the sandbox, e.g.
because they are encoded as offsets). This CL then also introduces a new
build flag, v8_enable_sandbox_future, which enables all future features.

This ports the trap handler implementation for the arm64 simulator
from POSIX to Windows. Apart from different registers being used
for passing parameters, and different access to these register
values in the signal handler, the implementation is exactly the same.
The new logic is being used for sanitizer builds which automatically
target arm64 via the simulator, or if manually compiling an arm64
simulator build on x64. I manually tested the latter.
Also, the existing unit test is enabled for Mac (which was missing)
and Windows now.

This adds some basic tests for WebAssembly code protection, in four
different configurations:
- no protection
- mprotect-based protection
- PKU-based protection
- PKU with fallback to mprotect
If PKU is not supported by the OS or hardware, then PKU is identical to
no protection, and PKU with fallback is identical to mprotect. We always
execute all four configurations anyway.
If protection is effective, we expect code to be writable within a
{CodeSpaceWriteScope}, and not writable otherwise. When trying to write
to non-writable code, we expect a crash of the process (checked via
{ASSERT_DEATH_IF_SUPPORTED}).

Whenever we are adding a new AddressRegion to the CodeMap, we first
remove all overlapping regions. The logic to check for overlapping
region is incomplete. For example, if all existing regions are less than
the region to be added, we incorrectly remove all regions, effectively
deleting all JITCodeEntry we have constructed.
We extract this overlapping check into a helper function, so that we can
unittest this without worrying about JITCodeEvent functionality, and also
without dealing with V8 internals (like Isolate and SFI).
The overlapping logic is rather hard to understand, has many special
cases, it will probably be much easier to just loop through all the
entries, rather than using lower_bound. Ideally, we can refactor this to
use some sort of sweep-line algorithm. Hopefully the unittests catch the
most obvious cases.

To consume a code cache off-thread
1. The embedder creates a CachedData object wrapping the data blob.
2. The embedder calls ScriptCompiler::StartConsumingCodeCache with the
CachedData, and receives a ScriptCompiler::CodeCacheConsumeTask
which takes ownership of the CachedData.
3. The embedder calls ScriptCompiler::CodeCacheConsumeTask::Run
on a different thread.
4. Once this completes, the embedded passes the completed task as an
optional argument into Source constructor, and calls Compile as
before.
This is roughly similar to how streaming compilation works, with the
QoL improvement that Source owns the CodeCacheConsumeTask and therefore
we can reuse the same Compile method and do the off-thread finalization
behind the scenes inside Compile.
On the v8::internal side, ScriptCompiler::CodeCacheConsumeTask wraps a
v8::internal::BackgroundDeserializeTask, which has a Run and a Finish
method. The Run creates a LocalIsolate (again, similar to
BackgroundCompileTask), calls some helpers on CodeSerializer, and stores
the pre-finalization result in a OffThreadDeserializeData structure.
This stores Persistent Handles to the off-thread initialized SFI and
a vector of Scripts needing fixing up, and it owns the PersistentHandles
object which owns those Handles. Finally, the Finish method consumes
this OffThreadDeserializeData structure, fixes up Scripts, moves the
SFI Handle into the caller HandleScope, and that's it.
Since we don't yet have the source at off-thread deserialization time,
the various code cache sanity checks are done without the source hash
when deserializing, and the Finish method re-does them now that the
source is available.

Due to a recent change Liftoff used different register configurations
in the pointer-compression and no-pointer-compression setups. This
caused a mismatch between the registers used by Liftoff and the
registers spilled by the WasmDebugBreak builtin.
With this CL the same register configuration is used both with and
without pointer compression. Even without x28 there are 24 registers
that can be used. Moreover, 24 registers can be spilled without
padding, which would be needed with 25 registers to preserve stack
alignment.
Drive-by change: Use Reglist in frame-constants on all platforms.

CsaLoadElimination failed to account for truncation when optimizing
loads. This CL extends the notion of compatible Loads and Stores to
include ({store}, {load}) pairs which both have integral representation
and {store}'s representation is no smaller than {load}'s. In case the
representations are not identical, it truncates and possibly
sign-extends {store} before forwarding it to {load}.
Additional change: Extend ObjectMayAlias with wasm allocating builtin
calls.

Currently if gn check is enabled (with v8/third_party ignored), there
are many errors due to headers being used without adding the proper
dependency in BUILD.gn (or because it's being used transitively without
a public_deps chain).
This makes the number of errors go from 2114 to 195.
Apart from adding dependencies, it also moves _v8_internal_Node_Print
from objects-printer.cc to node.cc so it can see the Node::Print method
which wouldn't otherwise be possible without a circular dependency. Also
removes the previously deleted compiler/graph-builder-tester.h file.
