This change generates functions that verify the things that Torque knows
about objects and their fields. We still must implement each verifier
function in objects-debug.cc, but we can call into the generated code to
verify that field types match their Torque definitions. If no additional
verification is required, we can use the macro USE_TORQUE_VERIFIER as a
shorthand for a verifier that calls the corresponding generated
function.
A new annotation @noVerifier can be applied to both class and field
definitions, to prevent generating verification code. This allows fully
customized verification for complicated cases like
JSFunction::prototype_or_initial_map, which might not exist at all, and
JSObject::elements, which might be a one pointer filler map.
Because Factory::InitializeJSObjectFromMap fills new objects with
undefined values, and many verifiers need to deal with partially-
initialized objects, the generated verifiers allow undefined values on
every class deriving from JSObject. In cases where stricter checks were
previously performed, they are kept in objects-debug.cc.

{NativeModule::GetCode} can actually return {nullptr} if no code was
compiled yet for a function, e.g. in asm.js where we use lazy
compilation. In that case, we must not try to increment the ref count
on the nonexisting code object.
We had a few errors recently that were hard to reproduce because we do
not have a flag to enable code logging. Clusterfuzz managed to
accomplish this by passing --trace-ic.
In order to test bugs in code logging properly, this CL introduces a
new runtime function called "EnableCodeLoggingForTesting". It registers
a noop {CodeEventListener} and enables code logging in the wasm engine.
We should whitelist this flag in ClusterFuzz to potentially flush out
more bugs.

This fixes the source position printed in the stack trace for exceptions
rethrown from within Wasm code. This only affects the message propagated
to the console, not the trace stored as part of the exception object.
Note that there still is a more fundamental issues with preserving the
original message of a caught exception and funneling it through to each
rethrow site, which is still missing. This change just makes sure that
the interpreter and TurboFan are consistent.

The original CL title was updated to reflect CL contents. The
--win64-unwinding-info flag still exists but it is set by default.
This is a reland of efd8c2d975
Original change's description:
> Remove --win64-unwinding-info flag and always generate unwind info on Win/x64
>
> The generation of unwind info to enable stack walking on Windows/x64
> (https://chromium-review.googlesource.com/c/v8/v8/+/1469329) was implemented
> behind a temporary flag, in order to coordinate these changes with the
> corresponding changes in Chromium.
>
> The required changes to Chromium
> (https://chromium-review.googlesource.com/c/chromium/src/+/1474703) have also
> been merged, so we can now remove the flag and enable the generation of stack
> unwinding info by default on Windows/x64.

A DCHECK in LookupIterator::name hits when we add a indexed property,
as it requires a named property.
This replaces it with GetName to avoid the failure.

There are two possible type:
- scriptParsed - breakpoint for any script,
- scriptWithSourceMapParsed - breakpoint for script with
sourceMappingURL.
When one of the breakpoints is set then for each matched script
we add breakpoint on call to top level function of that script.
