a067281d39 [modules] Implement recent ES revisions.
- Instantiation errors are no longer recorded. If instantiation fails,
  the module(s) are reset to "uninstantiated". When instantiation is
  re-attempted, the thrown exception will be fresh.
- Instantiation can succeed even where there are modules in the graph
  that previously failed evaluation.

a209dcf6a1 [api] Expose a module's status and exception.
V8 now takes care of recording a module's status, as proposed
in https://github.com/tc39/ecma262/pull/916.

486cd04f3d [modules] Allow resolve-callback to signal failure.
When asked for a module that previously failed to compile or
instantiate, the embedder necessarily has to signal failure.  In this
case, we expect an exception to be scheduled, which we will rethrow.

b0f5abbea3 [modules] Add an IsModule flag to ScriptOriginOptions.
Since the script origin is part of the key used in the compilation
cache, this ensures that the cache never confuses a module with a
non-module script.

9d2051fc28 [modules] Store Module metadata in per-Context EmbedderData
This is a re-land of https://codereview.chromium.org/2393303002/ with
an additional call to DisposeModuleEmbedderData() added to fix lsan failures.

Unifies the approaches used for storing the specifier -> module mapping
and the module -> directory mapping, using std::unordered_maps for both
and storing them per-Context.

This requires adding a method to the v8::Module API to get a hash code
for a Module, but allows slimming down the API in return: gone are
SetEmbedderData/GetEmbedderData, along with the fourth argument
to ResolveModuleCallback.

Besides a simpler API, this allows d8 to get closer to the HTML loader,
which requires each Realm to have a persistent module map (though this
capability is not yet exercised by any tests).

cf127e8144 [modules] Expand API to allow linking and use it in d8
This patch gives the ability for the embedder to ask for the
module requests of a module, and to pass a ResolveCallback
into Module::Instantiate().

In d8, I've implemented a simple module_map that's used
along with this API to allow loading, compiling, instantiating,
and evaluating a whole tree of modules.

No path resolution is yet implemented, meaning that all
import paths are relative to whatever directory d8 runs
in. And no imports are linked to the exports of the
requested module.

a18b797fd9 Enable compiling mjsunit tests as ES6 modules
Adding the line "// MODULE" to an mjsunit file will now cause
run-tests.py to prefix the test case with "--module" in the
d8 commandline.

d8 has itself been updated to treat files preceded with "--module" as
modules (that is, it compiles them with ScriptCompiler::CompileModule,
and turns on --harmony-modules).

70079dab13 Add basic compilation support for modules
This adds an "experimental" API hook (v8::ScriptCompiler::CompileModule)
allowing compilation of modules. The code gen is incredibly basic: the
module body is represented by a Block in the AST. But this at least gets
more of the pipeline working, and opens the door to writing mjsunit tests
(once d8 is modified to support module compilation).
