In order to implement eager (side effect free) evaluation of arbitrary
accessor properties correctly, we need the ability to call getters while
guaranteeing that we don't trigger side effects. This is accomplished by
adding a `throwOnSideEffect` flag to the `Runtime.callFunctionOn` API,
similar to what's already available with the `Runtime.evaluate` and the
`Debugger.evaluateOnCallFrame` APIs.

This change addresses inconsistencies wrt. to stepping into generator
functions and breaking on the implicit initial yield. The new behavior
is the following:
1. Stepping into a generator function doesn't trigger "generator
stepping", but rather pauses right before the initial yield
(assuming there a no non-simple parameters in between).
2. When paused on the initial yield and stepping into or over, we also
don't turn on "generator stepping" immediately, but rather return to
the caller and only enter "generator stepping" on SuspendGenerator
bytecodes that correspond to `yield`s or `await`s in the source
code.
This matches the stepping behavior of regular functions more closely and
seems like a good compromise.

Prior to this patch, regular expression objects with a monkeypatched
`toString` were printed using the `toString` result value, rather than
actually representing the regular expression’s contents.
const re = /./;
re.toString = () => 'whoops!';
console.log(re);
// → logs 'whoops!'
Now that `v8::RegExp::GetSource` properly escapes special characters in
the source pattern [1], just like `RegExp#toString`, there is no longer
any reason to avoid it.

This adds a new status file indicator "HEAVY" to mark tests with high
resource demands. There will be other tests running in parallel,
but only a limited number of other heavy tests. The limit is
controlled with a new parameter --max-heavy-tests and defaults to 1.
The change also marks a variety of tests as heavy that recently had
flaky timeouts. Heavy also implies slow, hence heavy tests are
executed at the beginning with a higher timeout like other slow tests.
The implementation is encapsulated in the test-processor chain. A
new processor buffers heavy tests in a queue and adds buffered tests
only if other heavy tests have ended their computation.

When setting a breakpoint on a line (in the DevTools front-end), the
front-end sends a columnNumber of 0 and the inspector automatically
resolves the actual location (in bytecode execution order). In order
to also support changing source code, the inspector memorizes a text
hint, and uses that to adjust the location upon reload. This hint was
however taken based on the original line and column numbers, rather than
the resolved location, which causes trouble when syntactic order doesn't
match execution order, as in case of `await o.m()`.
In order to address that we now remember the textual hint based on the
resolved location.

The callback IsolateData::ModuleResolveCallback, used by the fuzzer,
can return an empty MaybeLocal.
In this case v8::internal::SourceTextModule::PrepareInstantiate expects
it to have thrown an exception, and DCHECKs.
The fuzzer can hit this case because it doesn't load the entire module
graph before starting to tell V8 to instantiate modules. So if a module
fails to compile or load, another module trying to import it will hit
this DCHECK because we didn't bail out prior to module instantiation
like we should have.
This doesn't happen in Chromium because Blink loads the entire module
graph before trying to instantiate/link modules, ensuring that the
'real' ModuleRecord::ResolveModuleCallback never fails; indeed this is
mandated by the spec (see
https://html.spec.whatwg.org/#fetch-the-descendants-of-and-link-a-module-script).
To satisfy the fuzzer, this change makes
IsolateData::ModuleResolveCallback throw if it can't find the module.
Note, the bug's testcase doesn't involve import assertions. I don't
think this issue is new with my change
9d72d08a8c
but maybe that changed the crash stack or something in a way that
caused the issue to be reported.

The WebAssembly specification requires the "name" property of (exported)
function wrappers to hold the index of the function within the module,
and the default ToString algorithm for Function instances thus generates
something along the lines of `function 42() { [native code] }`, which is
technically correct, but not very useful to developers to diagnose
(humans don't think of functions in a module in terms of their indices).
With this CL, we change the description returned for Wasm (exported)

Previously we'd attach source positions to implicit returns that are
generated when leaving an async function with a promise rejection. This
was due to the use of `kNoSourcePosition` on the `end_position` in the
`ReturnStatement` nodes as indicator to pick the return position from
the function literal, instead of really not putting a source position on
that specific `Return` bytecode.
This CL adds a dedicated marker to `ReturnStatement` to express that the
`BytecodeGenerator` should put the return position from the function
literal there instead of overloading the meaning of `kNoSourcePosition`.

The "Restart frame" feature was implemented as part of LiveEdit and
primarily used to support LiveEdit of active functions, but that was
previously disabled as part of https://crrev.com/c/2846892 because it's
too brittle and causes crashes when using seemingly unrelated features.
The "Restart frame" feature was also available as a context menu item
separately in the DevTools front-end, but that was also already removed
as part of https://crrev.com/c/2854681 earlier. So all uses are gone
now.
This change works by marking Debugger.restartFrame as deprecated and
having it respond with a ServerError all the time. It thus allows us to
remove a whole bunch of machinery that was essentially just put in
various places to support the restart_fp_ magic. In particular the
debugger no longer needs any machine specific builtins now.

Previously we'd allow to replace the source of functions that are on the
current execution stack under certain conditions, but this has resulted
in an endless stream of bugs due to weird edge cases, and so we're now
limiting LiveEdit to functions that don't have any activation (including
not a suspended generator / async function activation).
We might eventually add the ability to LiveEdit functions with
activations and have them "upgrade upon next invocation", but that
doesn't seem to be an extremely important use case right now.

Prior to this patch, `new RegExp('a/b')` logs the following in
the DevTools Console:
/a/b/
This is syntactically invalid.
This patch fixes this while simplifying regular expression printing
in general by leveraging `RegExp#toString`, instead of duplicating
the logic on the inspector side. This is possible thanks to the recent
work on making `RegExp#toString` more robust (v8:1982).

This change slipped into https://crrev.com/c/2820970 and wasn't
intended. We actually need to rule out __proto__ here explicitly,
otherwise it starts showing up in previews for embedder objects
(i.e. for HTMLAllCollection, etc.).
