This CL moves collected source range information out of AST nodes
and into a side table stored on ParseInfo. The side table is only
created if block coverage is enabled, so there's almost no memory
overhead in the standard case.

This CL changes for floats what https://chromium-review.googlesource.com/c/558964/
changed for doubles.
Original message:
On x86, signalling NaNs get converted to quiet NaNs when they get push
on the stack and popped again. This happens in the code generation for
arm, specifically for the vmov instruction with the immediate parameter.
This CL replaces the vmov function in assembler-arm to take the
immediate as a uint64_t instead of a double, to guarantee that the bit
pattern does not change even if the parameter is a signalling NaN.
New in this CL:
Although src/double.h existed already, src/float.h did not exist yet.
I created the file in this CL, and moved the classes Float32 and
Float64 there, which already existed in src/deoptimizer.h.

This is the first step in optimizing Map and Set iterators. This ports
all the base functionality including
- Set.prototype.entries
- Set.prototype.values
- %SetPrototypeIterator%.next
- Map.prototype.entries
- Map.prototype.keys
- Map.prototype.values
- %MapPrototypeIterator%.next
to C++ and removes all the dead code and the previous half JavaScript
implementation. The next step is to port core parts to CodeStubAssembler
and finally inline the fast-paths into TurboFan directly. The relevant
design document is at:
https://docs.google.com/document/d/13z1fvRVpe_oEroplXEEX0a3WK94fhXorHjcOMsDmR-8
Most of this work is very similar to how the Array iterator works and we
mostly follow the same process for the implementation.

This splits the monolithic Apply builtin into several smaller builtins,
namely CallVargargs and ConstructVarargs, which accept a length and a
FixedArray of elements and deal with the actual stack manipulation, and
CallWithArrayLike / ConstructWithArrayLike that deal with getting the
elements from the receiver (for Function.prototype.apply, Reflect.apply
and Reflect.construct), which can now be written using the CSA.
The idea is that these builtins can be reused by TurboFan directly in
the future when we optimize apply better, and that we can also reuse the
core logic in the handling of spread calls/constructs.

This CL extracts the classes CompilationHelper, InstantiationHelper,

module-compiler.{h|cc}. This is necessary to introduce a
WasmCompilationManager which is known to the isolate and manages the
lifetime of all AsyncCompileJobs.
In addition to the mechanical changes of copying the code and splitting
class declaration from instantiation, I did the following changes:
* I renamed the CompilationHelper to ModuleCompiler.
* A finalizer function is passed to the InstantiationHelper as a
parameter.
* Adjusted UpdateDispatchTable in wasm-module.cc to make it available in
wasm-module.h, also with the internal signature.
* Duplicate the ResolvePromise/RejectPromise helper functions.
I did not rename InstantiationHelper because I could not come up with a
good name, and it could benefit from a small special refactoring anyways.

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.

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).

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.

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.

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

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.

I think that this CL breaks chromium compilation on windows with clang (). All other CLs in the list looks trivial and don't change test/unittest/BUILD.gn.

- Introduce new struct AsyncGeneratorRequest, which holds
information pertinent to resuming execution of an
AsyncGenerator, such as the Promise associated with the async
generator request. It is intended to be used as a singly
linked list, and holds a pointer to the next item in te queue.
- Introduce JSAsyncGeneratorObject (subclass of
JSGeneratorObject), which includes several new internal fields
(`queue` which contains a singly linked list of
AsyncGeneratorRequest objects, and `await_input` which
contains the sent value from an Await expression (This is
necessary to prevent function.sent (used by yield*) from
having the sent value observably overwritten during
execution).
- Modify SuspendGenerator to accept a set of Flags, which
indicate whether the suspend is for a Yield or Await, and
whether it takes place on an async generator or ES6
generator.
- Introduce interpreter intrinsics and TF intrinsic lowering for
accessing the await input of an async generator
- Modify the JSGeneratorStore operator to understand whether or
not it's suspending for a normal yield, or an AsyncGenerator
Await. This ensures appropriate registers are stored.
- Add versions of ResumeGeneratorTrampoline which store the
input value in a different field depending on wether it's an
AsyncGenerator Await resume, or an ordinary resume. Also modifies
whether debug code will assert that the generator object is a
JSGeneratorObject or a JSAsyncGeneratorObject depending on the
resume type.

* Assumes 'use asm' is the only string.
* Does not handle unicode for now (tools don't emit it).
* Combines global + local string table with lexer.

This is another step towards making calls to builtins more convenient.
Builtins::CallableFor is an automatically generated Callable accessor for TFS
builtins (whereas previously we had to manually add an accessor to
code-factory.{h,cc}).
CSA::CallBuiltin is a convenience wrapper around CallStub for TFS builtins.
We can begin removing accessors for TFS builtins from CodeFactory in an
upcoming commit.
