The text representation of that opcode is "memory.grow", so the macro
should also be called WASM_MEMORY_GROW. This is also consistent with
WASM_MEMORY_SIZE.

This is a speed-for-memory tradeoff, which can be achieved by
re-mapping the builtins code blob into existing code range.

This CL handles cases where both embedded and un-embedded off-heap
builtins' PCs might appear on the call stack.

The v8_enable_short_builtin_calls build flag is still disabled.

One of the x86 ISA extensions is confusingly named SSSE3 (*Supplemental*
Streaming SIMD Extensions 3). SSSE3 supersedes SSE3, and is superseded
by SSE4.

This CL adds testing coverage for x86 CPUs that support SSE3
instructions, but do not support SSSE3 instructions. Chrome supports
these CPUs, and they are used by a non-trivial amount of Chrome's users
on Windows. This CL aims to cover all the spots missed by
https://crrev.com/c/2757893.

Previously, GCInfoTrait relied on the non-trivial constructor of a
static object for registering a new GCInfo object. The generated code
is required to be thread-safe which is achieved by introducing guard
variables in the compiler.

The new version is similar to Blink in that it relies on zero
initialization of a trivially constructible atomic.

Compared to guard variables that are created per GCInfo registration,
the atomic creates less bloat (~20bytes/type) and also results in a
better fast path.

re-mapping the builtins code blob into existing code range.

The feature can be enabled by v8_enable_short_builtin_calls flag and
it's off by default.

This CL adds GN flag and updates code generator to emit shorter
pc-relative calls/jumps to builtins. However, the runtime doesn't
support appearance of the off-heap builtins' PCs that point to the
embedded code blob on the stack yet.

In wasm-compiler, nodes that reference the Isolate and Instance should
depend on whether the current frame JS or Wasm. This was implemented
with mutable fields caching nodes in WasmGraphBuilder and its
subclasses, but was not done consistently.
This CL removes all mutability and replaces it with an additional field
isolate_ in WasmGraphBuilder, which is only set in the constructor of
the child class WasmWrapperGraphBuilder.

Additional changes:
- Remove three almost-unused utilities from WasmGraphAssembler.
- Reduce duplicate BuildImportCall with int index argument to the one
  with Node* index argument (the additional operations should be
  optimized away).

This CL implements the above in a concurrent setting without relying
on serialization (except existing serialization to read a consistent
JSObject state, which should be addressed in future work).

There are three main cases in which GetOwnConstantElement can succeed:

- Frozen elements are always constant. The backing store is immutable
after initialization and can be accessed through relaxed reads.
- String wrapper elements are always constant. The JSPrimitiveWrapper
is immutable after initialization, and internalized Strings are
protected by a mutex (other string kinds are currently not handled).
- Dictionary elements may be constant. Since this case is not
particularly important for the optimization, we leave it unimplemented
for now.

Add a test for a module without a start function; in that case, we want
to break when first calling into the module (via an exported function).

macOS’s `readlink` doesn’t support the `-f` flag. By using `realpath`
we get the same functionality with added support for macOS.

Finally, this patch adds `v8` and `v8-debug` to the completion
command. These are the binary names used by jsvu [1].
