Original Commit Message:

    Adds support for emitting data with a reloc info to enable support
    for HeapObjects for immediate deopt args, required by dynamic check maps.

    In order to do this, a new DATA_EMBEDDED_OBJECT relocinfo type is added.
    This represents a raw object inserted into the instruction stream. For
    x64/ia32 it is treated the same as FULL_EMBEDDED_OBJECT, but on
    Arm/Arm64 this behaves differently since it points directly to the
    embedded object pointer rather than to an instruction that loads it.

For i64x2.ext_mul and i16x8.ext_mul, we can simply call the
macro-assembler functions.

For i32x4.ext_mul, the macro-assembler requires that dst == src1 if AVX
is not supported, so we add a helper function to do that check, and make
sure dst == src1 before calling into macro-assembler.

This is the same implementation as x64 (https://crrev.com/c/2603765).

Design doc:
https://docs.google.com/document/d/1xkXj94iExFgLWc_OszTNyNGi523ARaKMWPZTeomhI4U
A lot has changed since the last patchset! I recommend revisiting this
design doc and reading the parts in green. I explain the roadmap for
what changes to expect from ETW instrumentation as well as the
instrumentation of this particular CL.

I'll do my best to answer any further questions anyone has about my
particular instrumentation or ETW in general :)

---

This is the first of a series of changelists to round out ETW
instrumentation for V8.

This changelist represents the most minimal change needed to instrument
ETW in V8. In particular, it:
  - defines and registers the ETW provider,
  - interacts minimally with the rest of V8, by hooking into the
    existing TracingController::AddTraceEvent function,
  - is designed with a platform-agnostic layer, so that event tracers
    for other platforms can be instrumented in teh future.

Some notes on instrumentation (aka I copied stuff from the design doc):

We make heavy use of the TraceLogging API to log events. It differs from
previous methods of emitting ETW events in that it doesn<E2><80><99>t
require the overhead of a separate manifest file to keep track of
metadata; rather, events using this API are self-descriptive.

Here are the five major steps to instrument the TraceLogging API:
  - Forward declare the provider (from provider-win.h)
  - Define the provider in a .cc file (from provider-win.cc)
  - Register the provider (called from v8.cc).
  - Write events (called from libplatform/tracing-controller.cc)
  - Unregister the provider (called from v8.cc)

At the base, we have an abstract provider class that encapsulates the
functionality of an event provider. These are things like registering
and unregistering the provider, and the actual event-logging.

The provider class is split into provider-win and provider-mac
(currently not instantiated) classes, with OS-dependent implementations
of the above functions.

In particular, the TraceLogging API is used only in provider-win. It is
here that we forward declare and define the provider, as well as write
ETW events.

Finally, there is a v8-provider class that serves as a top-level API and
is exposed to the rest of V8. It acts as a wrapper for the
platform-specific providers.

The .wprp file is needed so that Windows Performance Recorder knows how
to capture our events.

Some considerations:
  - Is TracingController::AddTraceEvent the best place from which to
    write my events?
  - Is src/libplatform/tracing the best place to put my instrumentation?
  - Right now, I fail the preupload because of this, which tells me my
    files are probably not in the best location:

You added one or more #includes that violate checkdeps rules.
src\init\v8.cc Illegal include: "src/libplatform/tracing/v8-provider.h"
Because of "-src/libplatform" from src's include_rules.

The negative implication from --single-threaded to --liftoff was
introduced because with --single-threaded, no tier-up to TurboFan is
possible, and TurboFan provides faster code and smaller code

This CL removes this implication. The reason is that this implication
does not only define the default compiler for --single-threaded to
TurboFan, and also completely disables the option to use Liftoff
instead. By removing the implication, and embedder who uses
--single-threaded can decide by themselves if they want to use Liftoff
by setting --liftoff, or if they don't want to use Liftoff by setting
--no-liftoff.

According to the Torque definition, the type of the 'source' field is
'String|Undefined'. The Factory only allowed to pass a string though,
which forced us to set an empty string for wasm scripts.

This CL changes the factory to also allow undefined values, which fits
slightly better for wasm.
The inspector needed a minor change to handle undefined source like an
empty string.

Previously the proxies that make up the DebugEvaluate implementation for
Wasm frames lived in wasm-js.cc, but that was quite confusing since

(a) the rest of the debug support for Wasm lives in wasm-debug.cc (and
    we intend to eventually unify the DebugEvaluate and Scope objects),
    and
(b) the wasm-js.cc file is explicitly about the WebAssembly JS API
    that's part of the WebAssembly specification, and the DebugEvaluate
    proxies aren't part of that.

The wasm-scope-info-liftoff.js and wasm-set-breakpoint-liftoff.js tests
were originally testing the Liftoff path (when we still had the Wasm
interpreter), and have received some updates along the way. Nowadays the
interpreter is going and the non-liftoff versions of these tests don't
provide any additional test coverage, but are merely a slightly less
updated version of the liftoff test.

These optimized macro-assembler functions were introduced in
https://crrev.com/c/2591853. Reuse them in Liftoff to get better
code-gen, especially when AVX is supported. The macro-assembler
functions have no alias requirements, so we can pass dst and src
directly without doing any checks or moves.

In https://crrev.com/c/2591859 we changed the way we generate code for
v128.select, which assumes that all inputs are registers. We did not
update the instruction selector with this new constraint.

For i64x2.ext_mul and i16x8.ext_mul, we can simply call the
macro-assembler functions.

For i32x4.ext_mul, the macro-assembler requires that dst == src1 if AVX
is not supported, so we add a helper function to do that check, and make
sure dst == src1 before calling into macro-assembler.
