fc3f29d329 Reland of Reland of "ARM64: Add NEON support"
This reverts commit c5aad5f284
The CL was reverted due to missing Chromium dependencies.

This commit removes the simulator trace-based tests, and the associated header file dependencies, previously pulled in by DEPS. The NEON support now has only hand-written tests, in test-assembler-arm64.cc. The remaining tests can be added in a later patch.

737962f85b [wasm] [cleanup] Avoid lazy initialization of arrays
Both lazy initialization and static initialization (via static
initializer) are bad. Fortunately, the arrays we are constructing are
constant anyway, so we can just compute them at compile time. This is
enforced by making them constexpr.
This also saves all code needed for the initialization, and makes
accesses to the tables faster, as they don't need any atomic operations
(via LazyInstance).

73ab0f4b9f [gn] Allow building a snapshot with unwinding information.
Add a new "v8_perf_prof_unwinding_info" option to gn that translates to building
the snapshot with "--perf-prof-unwinding-info". It allows unwinding TF generated
code from the snapshot.

Additionally, add a warning if one uses the option along with a snapshot which
was not build with unwinding information.

Running tests in this configuration revealed an issue in the checks performed
when accessing the stub cache. We would assume that the `Code::Flags` bitfield
only contains the `Kind` and `ExtraICState` fields, when there is also a
`HasUnwindingInfo` field which can now be set for stubs.

cb7dd0a911 Replace sanitizers:deps with exe_and_shlib_deps (v8)
All targets (at least on sanitizer builds) unconditionally depend
on //build/config/sanitizers:deps.

It is necessary for bug 593874 that all targets now also depend
on //buildtools/third_party/libc++:libcxx_proxy.  This requires
adding a new "global dependency": //build/config:exe_and_shlib_deps.

This CL updates references to sanitizers:deps to instead refer to
//build/config:exe_and_shlib_deps.

4becbe345f [ignition] Change --trace-ignition to a runtime flag
Generate the code (extra runtime calls) for --trace-ignition support at
compile time, based on a #define (similar to TRACE_MAPS). Then check for
--trace-ignition at run-time when deciding whether to actually print
anything. This should make --trace-ignition less painful to use.

Note that --trace-igition is disabled by default, even on debug builds.
It has to be enabled with the gn arg "v8_enable_trace_ignition=true"

As a drive-by, TRACE_MAPS is renamed to V8_TRACE_MAPS, for consistency,
and SFI unique index (needed both by --trace-ignition and --trace-maps)
is cleaned up to be behind another #define.

72019a0428 [wasm] Streaming decoder
This CL implements a streaming decoder which takes the bytes
of a wasm module as an input, potentially split into multiple
chunks, and decodes them into segments. Each segment either
contains the payload of a whole section, or the code of a
single function. The goal is that the streaming decoder is
used for streaming compilation. That's where the interface
comes from, see
(https://cs.chromium.org/chromium/src/v8/include/v8.h?q=OnBytesReceived&sq=package:chromium&l=4060)

Error positions are not reported correctly at the moment. I
plan to do this in a separate CL.

c6816cd87d [heap] Implement simple concurrent marking deque.
This patch adds a concurrent marking deque that exposes the same interface
for the main thread as the existing marking deque.

The matching interface makes the concurrent marking deque a drop-in
replacement for the sequential marking deque without any change in
mark-compactor and incremental marker.

0ca84d06f5 Revert "[intl] Switch to using declared accessors"
This reverts commit 4968b2c4d1.

Reason for revert: Speculative revert for severe perf regression
https://bugs.chromium.org/p/chromium/issues/detail?id=716468#c3

Original change's description:
> [intl] Switch to using declared accessors
> 
> This patch cleans up the Intl code by switching to using declared
> accessors, rather than embedder fields, for holding references to
> ICU objects. Additionally:
> - Rename classes to be more similar to how other classes are named
> - Make some unreachable paths into check-fails, rather than throwing
>   JS exceptions
> - Move some macros from objects-inl.h into object-macros.h, to allow
>   the implementation here to not touch objects.h
> - Some setup logic is moved from runtime-i18n.cc to i18n.cc.
> 
> This patch leaves type tags as they are; a future patch should move
> from a special Intl type tagging system to object types as other system
> objects use. Future patches should also move more logic to i18n.cc

e671ed3610 Decouple root visitors from object visitors.
This patch adds a new interface called RootVisitor and changes the root
iteration functions to accept a RootVisitor instead of an ObjectVisitor.

Future CLs will change ObjectVisitor to provide the host object to all
visiting functions, which will bring it in sync with static visitors.

Having separate visitors for roots and objects removes ambiguity in
VisitPointers and reduces chances of forgetting to record slots.

This is intended as pure refactoring. All places that require behavior
change are marked with TODO and will addressed in future CLs.

e8df147f2b [wasm] [cleanup] Move LocalDeclEncoder to own compilation unit
wasm-macro-gen.h is mainly used from tests, but LocalDeclEncoder is
also used from various other places.
This CL moves the LocalDeclEncoder to an own compilation unit. We want
to later move wasm-macro-gen.h to the tests folder.
It also refactors the LocalDeclEncoder to reuse the
LEBHelper::write_u32v and LEBHelper::sizeof_u32v methods instead of
reimplementing it.

f28e487858 [console] fast console.assert(true)
A lot of web sites around the world has hack which replaces native console.assert by function with fast return.
Current console.assert is slow because we need to run CPP builtin but we should enter this builtin iff condition is false or omitted.

54271c21e2 [inspector] move console to builtins
What will we get:
- console would be included into snapshot and allow us to reduce time that we spent in contextCreated function (~5 times faster),
- it allows us to make further small improvement of console methods, e.g. we can implement super quick return from console.assert if first argument is true,
- console calls are ~ 15% faster.
