We currently hit a nullptr access when trying to update the detected

unnecessary overhead in production code), we just pass a pointer when

The Isolate is only used to access the wasm engine, and the accounting
allocating. The latter is also linked directly from the wasm engine, and
the engine is linked from the native module, to which the DebugInfoImpl
already has access.
Hence, this CL removes the redundant Isolate pointers, and just accesses
the engine and the allocator via the NativeModule.

There are only three tests with differing behaviour if Liftoff is used
for debugging.
This CL thus stages the --debug-in-liftoff flag behind --future (tested
by the "future" variant) and excludes the three tests.
This allows us to test the other (already working) tests for
regressions, and iteratively shrinking down the list of failing tests.
Drive-by: Tier down modules in tests before testing debugging features
to avoid hitting a DCHECK in Liftoff recompilation for debugging.

Currently there are two ways wasm locations are represented in the
inspector. This remains unchanged for now. Also, currently there are
multiple ways location is represented within V8, with the line number
sometimes being a function index and sometimes being 0, and the column
number being a byte offset which is sometimes function relative and
sometimes module relative. With this change, the line number is never
used within V8 (it is always 0), and the column number is always a
byte offset from the beginning of the module. This simplifies
translation logic and keeps it in one place, and will simplify future
changes to wasm location representation in the inspector API.

The interface of {WasmCompiledModule} currently mostly receives and

This leads to performance and memory overhead for chained accesses like
{instance->compiled_module()->shared()->script()}, because intermediate
accessors allocate Handles for no reason. It also breaks the
constraints that lower-case accessors should be trivial to execute, but
allocating a handle is not trivial (should not be done in a loop if not

This CL (finally) makes the contract between the compiler and the module
environment clear. In order to compile a function, the caller must provide
an instance of the compiler::ModuleEnv struct, which contains references
to code, function and signature tables, memory start, etc.

This CL consolidates ownership of parameters used to compile code (which
we always specialize) in 2 places:
- ModuleEnv for compile-time data
- WasmCompiledModule for runtime data
The parameters in question are: memory size and start; globals start;
address of indirect function tables (and their signatures, respectively);
and address to be used for wasm call sites.
Ideally, we'd collapse this down to one place, however, we need
specialization data to survive serialization. We can achieve this we get off
the GC heap and use a different wasm code serializer.
The CL:
- removes aliasing of parts of the specialization data, and moves
to using ModuleEnv as a token of passing around compile-time data, instead
of a mixture of ModuleEnv, WasmInstance, and some other structures. ModuleEnv
is responsible for providing a consistent view of the specialization data,
e.g. valid memory sizes (multiples of page size), and matching sized function
tables and signatures.
- removes WasmInstance, as its data is now contained by ModuleEnv.
- removes ModuleBytesEnv. We now pass the wire bytes explicitly. They can't
always be assumed as present (e.g. streaming compilation), and probably more
refactoring may need to happen once streaming compilation lands and we
better understand our dependencies.

My goal was to move breakpoint API to native with minimal changes around, so on inspector side we use v8::debug::BreakpointId instead of String16, on v8::internal::Debug we use i::BreakPoint object instead of break point object created inside of debug.js.
There are a lot of opportunities how we can improve breakpoints (at least we can avoid some of linear lookups to speedup implementation) but I think that as first step we need to remove mirrors/debug.js APIs.
Drive by: debugger-script.js and usage of debugger context in inspector code base.
