Moved the compilation/instantiation pipeline to work off the
module object (JSObject), making the compiled module data (the
FixedArray) an implementation detail. This:
- simplifies the code by removing duplicate decode->compile->instantiate
sequences
- sets up the stage for "dressing up" the runtime model with
stronger typed APIs
- helps relanding this CL: https://codereview.chromium.org/2305903002/.
It turns out that GCs during the cloning/instantiation events cause
trouble, and centering the source of truth on the module object helps
address this issue.
In the process, clarified cctest setup for wasm-capable isolates,
and changed signatures for consistency (using ModuleOrigin througout).

With this CL the wasm-code-fuzzer first decodes and interprets the test
case generated by the fuzzer. It then compiles the test case, but only
executes the compiled instance if the interpretation of the test case
was successful. If the compiled instance is executed, then the result of
the execution is compared with the result of the interpretation.
Additionally this CL refactors the CompileAndRunWasmModule function in
wasm-module.cc to resuse code in the call to the interpreter.

This adds:
* A script (tools/update-wasm-fuzzers.sh), which creates a new fuzzing seed
corpus and uploads to google storage (you must have the right credentials).
* A new pair of DEPS entries to pull in the current version of the corpus
based on a checked in pair of hash files.

This makes us able to get rid of dependencies to parser.h from places
which only need the ParseInfo, and also gets rid of the curious Parser
<-> Compiler circular dependency.
Also IWYUd where necessary.

Thrown exceptions must be handled before another exception is thrown.
This fixes all remaining test failures exposed by not clearing pending
exceptions in JSEntryStub.

Remove second wasm module compilation and instantiation path that
we had in CompileAndRunWasmModule and reuse the same path used
by user code.

This allows using icu data, bundled in the icudtl.dat file,
to be loaded automatically from a default location
side-by-side with the executable.
The v8 stand-alone default is still to use statically
linked ICU data, but this will be switched in a separate
follow-up CL.

This adds the v8-side fuzzer executables for smoke testing.
This also renames the old gyp targets to stay consistent
with chromium.
Naming convention for type X after the rename:
library: X_fuzzer (gn), X_fuzzer_lib (gyp)
executable v8: v8_simple_X_fuzzer
executable chromium: v8_X_fuzzer

This prepares for pulling chromium's build as dependency for
gn. After this, the files in build and gypfiles need to stay
in sync until chromium is updated.

This will allow to pull in gyp as a deps to the same location
as chromium (tools/gyp not build/gyp), needed for gn switch.
This is the first step of a 3-way move.
1) Copy v8.gyp in v8
2) Update references in embedders (follow up)
3) Remove old v8.gyp (follow up)

We expect that the majority of malloc'd memory held by V8 is allocated
in Zone objects. Introduce an Allocator class that is used by Zones to
manage memory, and allows for querying the current usage.
