The name {CallerOwnedBuffer} does not make sense in all situations,
especially if such an object is returned instead of being passed as
argument.
I am working on moving the wasm wire bytes off the JS heap, and hence
will return unowned references via the API. To prepare this change, I
deprecate the existing {CallerOwnedBuffer} and introduce a new
{BufferReference} struct with proper field names.

As specified in https://tc39.github.io/ecma262/#sec-atomics-wait, the
critical section must occur before the load and comparison.
This slightly changes the `AtomicsWaitCallback` API, but in a
direction that arguably makes it more consistent.
As a drive-by fix, reset `node->waiting_` in case there
was an exception from the first callback.

This extends the ScriptCompiler::CompileModule function with a
CompileOptions argument. Accepted values are kNoCompileOptions (in
which case, behavior remains unmodified) and kConsumeCodeCache. If the
latter is passed, we try to fetch the given module from the code
cache.
Since it is possible to compile the same source code as both a script
and a module (and different code is generated for the two cases), a
new is_module bit is added to the SerializedCodeData header to
disambiguate between the two cases.

The current profiling mode (called kLeafNodeLineNumbers in this CL)
produces a tree, with each node representing a stack frame that is seen
in one or more samples taken during profiling. These nodes refer to a
particular function in a stack trace, but not to a particular line or
callsite within that function.
This CL adds a new more (called kCallerLineNumbers) which produces a
different profile tree, where each stack trace seen during profiling,
including the line number, has a unique path in the tree.
The profile tree was previously keyed on CodeEntry*. Now it is keyed on
the pair of CodeEntry* and line_number, meaning it has distinct nodes
for those combinations which exist, and each distinct stack trace that
was sampled is represented in the tree.
For optimized code where we have inline frames, there are no line
numbers for the inline frames in the stack trace, causing duplicate
branches in the tree with kNoLineNumberInfo as the reported line number.
This will be addressed in follow-ups.

This method is intended for use by code caching as follows:
1. The module is compiled (and perhaps instantiated).
2. The embedder fetches and stores the module's unbound script (i.e.
the shared function info).
3. Module evaluation, maybe triggering lazy compilation.
4. Generated code for the module (which hangs off the shared function
info) is inserted into the code cache.
Subsequent module loads can load from the code cache prior to
evaluation.

Replace all uses with V8_WARN_UNUSED_RESULT.
WARN_UNUSED_RESULT was defined in src/base/compiler-specific.h, which

This exposes new flags to allow embedders to whitelist callbacks as
side-effect-free during evaluation with throwOnSideEffect.
Accessors and Functions/FunctionTemplates can take a new param on:
- v8::Object::SetNativeDataProperty
- v8::Object::SetLazyDataProperty
- v8::Object::SetAccessor
- v8::FunctionTemplate::New
- v8::FunctionTemplate::NewWithCache
- v8::Function::New
While Interceptors can be created with an additional flag:
PropertyHandlerFlag::kHasNoSideEffect
