91b102c763 [test][cleanup] Rename WASM_*_LOCAL to WASM_LOCAL_*
The opcodes were renamed long ago, but the macros were still using the
old syntax.

This CL was created using the following command (for WASM_GET_LOCAL,
    WASM_SET_LOCAL, and WASM_TEE_LOCAL):
ag -l WASM_GET_LOCAL | xargs -L 1 sed -i 's/\bWASM_SET_LOCAL\b/WASM_LOCAL_SET/g'

Add a separate mutex for the {debug_side_tables_} field. This ensures
that we can use {GetDebugSideTableIfExists} even if {mutex_} is already

1a82a10ba0 [wasm][debug] Pass pointer for detected features
We currently hit a nullptr access when trying to update the detected
feature set. Instead of adding a check for nullptr there (which would be
unnecessary overhead in production code), we just pass a pointer when
compiling for debugging.

a7a201b260 [wasm][debug][cleanup] Remove redundant Isolate parameter
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.

0f4d68dac9 [wasm][debug] Stage --debug-in-liftoff behind --future
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.

3c98a2a36a [wasm] Prevent breakpoints on nonbreakable positions
If a breakpoint is set on a non-breakable position, the wasm interpreter
just stores the value 0xFF (kInternalBreakpoint) in the function body
(actually, a copy of the function body). This might overwrite immediates
and cause subsequent failures in the wasm interpreter.

In JavaScript, breakpoints are just forwarded to the next breakable
position. This CL implements the same for WebAssembly.
A cctest tests this behavior, and the existing
wasm-stepping-byte-offsets.js inspector test is extended to also set the
breakpoint within an i32 constant immediate.

5c23e6b5f2 V8 Wasm locations should always be based on byte offsets
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.

we still use the old wording.

This renaming is mostly mechanical.

  xargs -L1 sed -E 's/kExpr(Get|Set|Tee)Local\b/kExprLocal\1/g' -i

This CL re-enables that warning, and fixes all current violations by
adding an explicit "NOLINT(runtime/references)" comment. In follow-up
CLs, we should aim to remove as many of them as possible.

b9b4b8798f [wasm] Merge {WasmSharedModuleData} with {WasmModuleObject}
The {WasmSharedModuleData} struct was introduced to hold data common to
all wasm instances belonging to the same module. The idea was to keep
"internal state" separate from the JS-facing {WasmModuleObject}. Since
this objective has no real value, and we already store some internal
data on the {WasmModuleObject}, this CL merges these two objects.

8466b71ad8 [wasm] Split off wasm-linkage.h
Linkage-related methods were declared in wasm-compiler.h and
implemented in wasm-linkage.cc. This required all users of e.g. wasm
call descriptors to include the whole wasm compiler header. Also, some
wasm linkage information is independent of turbofan and also used
outside of the compiler directory.

This CL splits off wasm-linkage.h (with minimal includes) and puts it
in src/wasm. This allows to use that information without including
compiler headers (will clean up several uses in follow-up CLs).

a1fcd77714 [wasm] Dehandlify WasmCompiledModule interface
The interface of {WasmCompiledModule} currently mostly receives and
provides handles to the contained data. Other interfaces don't (see
{object-macros.h}.
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
needed).
It also silences gcmole errors, as documented in
https://crrev.com/c/832268.

Abstract equality comparison of a BigInt and a String converts the

without throwing an exception.
This CL uses the existing ShouldThrow enum to configure behavior of
String-to-BigInt conversion, moving it out of Object into globals.h.

f9d4090b4b [wasm] Consolidate ownership of instantiation/specialization parameters
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.
