The verbose output shown on bots didn't print the first failing result
of a flaky test before. Now the result line shows all results and
the details in the end show the output of the first failure.
Previously it was confusing as it seemed that the json results and
the test runner output differed.
We now print PASS in all caps like the other statuses. A test for
this case already existed and the output is now updated.

This changes the test runner to automatically treat cases in which
both a flag and its negation are present as a flag contradiction.
Example: "--foo --no-foo".
With this change it's no longer necessary to explicitly specify these
trivial contraditions in variants.py.
Note: since negations are created through simple string operations,
bogus constructions are possible ("--nobodys-perfect" ->
"--bodys-perfect"). We accept these as unlikely-to-cause-problems.

This adds a new status file indicator "HEAVY" to mark tests with high
resource demands. There will be other tests running in parallel,
but only a limited number of other heavy tests. The limit is
controlled with a new parameter --max-heavy-tests and defaults to 1.
The change also marks a variety of tests as heavy that recently had
flaky timeouts. Heavy also implies slow, hence heavy tests are
executed at the beginning with a higher timeout like other slow tests.
The implementation is encapsulated in the test-processor chain. A
new processor buffers heavy tests in a queue and adds buffered tests
only if other heavy tests have ended their computation.

We used to recompile WasmCapiCallWrappers whenever they were
needed, but never garbage-collected them, which caused a memory
leak when many short-lived instances of the same module were
created. This patch makes the wrappers cacheable and caches them,
which avoids both repeated compilation effort and the unbounded
memory growth.
Drive-by cleanup: unify WasmCapiFunctionData with the other
Wasm*FunctionData classes by making it inherit from WasmFunctionData.

tldr: This adds an on-demand comparison with x64 when a difference to
a non-x64 build is detected.
Normally foozzie compares the baseline build (just ignition), with
two secondary builds. One, the default, always uses the shipping
configuration, the second passes additional flags. Both can use a
different architecture than the baseline build as well.
Differences between ignition and turbofan are then often detected
independent of the architectures used, but reported several times
(for each compared architecture).
This makes the reporting more specific, by running another build on
demand that uses the baseline architecture, but otherwise the same
configuration that showed a difference. If it shows the difference as
well, the baseline architecture is used for the report.
As a result only pure architecture differences will be reported with
an architecture other than x64.
This also adds some minor refactorings to reduce the code complexity
when looping over comparisons.
For testing this, the fake-d8s are extended with different behavior
for different flags passed. We add two test cases for testing:
x64 vs. ia32 with difference in x64 and ia32
x64 vs. ia32 with difference only in ia32

This test attempted to call mprotect to switch memory permissions,
which returns an error on MacOS on arm64. The workaround is simple:
don't call mprotect, rely on MacOS-specific permission switching.

The pointer compression cage is the virtual memory reservation
that all compressed pointers fall within. This CL splits pointer
compression into two modes: a per-Isolate cage and a shared cage
among multiple Isolates.
When multiple Isolates are sharing a cage, they can decompress
each others' pointers and share the same virtual memory range.

This CL adds features to pack/unpack map words.
Currently V8 cannot store extra metadata in object headers -- because V8
objects do not have a proper header, but only a map pointer at the start
of the object. To store per-object metadata like marking data, a side
table is required as the per-object metadata storage.
This CL enables V8 to use higher unused bits in a 64-bit map word as
per-object metadata storage. Map pointer stores come with an extra step
to encode the metadata into the pointer (we call it "map packing").
Map pointer loads will also remove the metadata bits as well (we call it
"map packing").
Since the map word is no longer a valid pointer after packing, we also
change the tag of the packed map word to make it looks like a Smi. This
helps various GC and barrier code to correctly skip them instead of
blindly dereferencing this invalid pointer.
A ninja flag `v8_enable_map_packing` is provided to turn this
map-packing feature on and off. It is disabled by default.
* Only works on x64 platform, with `v8_enable_pointer_compression`
set to `false`

Some includes that were recursively included by wasm headers needed to
be added explicitly now.
backing-store-unittest.cc is renamed to wasm-backing-store-unittest.cc

Building arm64 binaries on arm64 hosts works as long as you set
the correct options in args.gn. This patch teaches gm.py to do
that.
Building 32-bit arm binaries on arm64 hosts requires an extra
definition in snapshot_toolchain.gni (as well as some system
setup to support running 32-bit binaries).

This change relands the last part of https://crrev.com/c/2601880 .
ScopeInfo has a vestigial 'length' field from when it used to be a
FixedArray. This change removes that field, which saves some memory.
More specifically:
- Make ScopeInfo inherit from HeapObject, not FixedArrayBase which
supplied the 'length' field.
- Change FactoryBase::NewScopeInfo to allocate the updated object shape.
It maintains the existing behavior of filling the newly-allocated
object with undefined, even though that's not a valid ScopeInfo and
further initialization is required.
- Change a few length computations to use HeapObject::kHeaderSize rather
than FixedArray::kHeaderSize.
- Remove an unnecessary heap verifier function.

This removes all wasm includes from src/debug and src/inspector if
webassembly is disabled (v8_enable_webassembly=false). It also removes
the definition of {WasmValueObject} and {v8::debug::WasmScript}.
This will allow to later fully exclude the src/wasm directory from
compilation (once other components are fixed).

Split out all the headers from v8_compiler/v8_compiler_opt and
v8_base_without_compiler into v8_internal_headers since the headers
have inter-dependencies that otherwise make it impossible to satisfy gn
check.
Also adds new v8_header_set torque_runtime_support that exports
src/torque/runtime-support.h separately from the generated headers.
This reduces the number of gn check failures from 169 to 59.
