The new ArrayBufferCollector class tracks these dead allocations.

- WasmCode represents code, including reloc info. It holds wasm

Streaming compilation started the compilation of a module at the
beginning of the code section. However, there exist valid modules which
do not contain a code section. In this CL we check for the existence of
a code section when we finish the stream. We do this by checking if the
module compiler in the AsyncCompileJob exists, because the module
compiler gets initialized at the beginning of the code section.
If we detect that compilation has not been started because there was no
code section, then we start compilation when the stream finishes.

For the fast case we can avoid the instance type check, since the map
check covers that. We also don't need to call out to the ToBoolean
builtin in general, but just use the BranchIfToBooleanIsTrue logic.
Plus in the fast case, we don't know that the JSIteratorResult::done is
a boolean, since the map doesn't guard this assumption, so we also need
to do a proper BranchIfToBooleanIsTrue in that case.

This does not guarantee that immortal immovable objects

The existance of an `AllowJavascriptExecutionDebugOnly` scope in
`Isolate::ReportPendingMessages()` indicates that the API supports
running arbitrary JS code in a `AddMessageListener` callback.
Currently, this can fail in debug mode: The
`!isolate->external_caught_exception()` condition is checked when
entering API methods inside such a handler. However, if there is
a verbose `TryCatch` active when the exception occurs, this
check fails, and when calling `ToString()` on the exception object
leaves a pending exception itself, the flag is re-set to `true`.
Fix this problem by clearing the flag and the pending exception if
there was one during `ToString()`. This matches the code a few lines
up in `messages.cc`, so the exception state is now consistent
during the callback.
This currently makes a Node.js test fail in debug mode
(`parallel/test-error-reporting`).

This CL creates the invariant that the BigInt class treats
BigInt objects as immutable. Writing to new BigInt objects
as part of their construction is done by the MutableBigInt
helper class, which in turn is hidden as an implementation
detail in bigint.cc.
As a side effect, this refactoring enforces right-trimming
checks for all newly created BigInts, and ensures that all
BigInt allocations possibly exceeding kMaxLength check for
this case and throw a RangeError instead of crashing.

the instance size and the in-object properties count.
This patch replaces the in-object properties count byte in the map
with the byte that stores the start offset of in-object properties.
The new byte can be used in the layout descriptor to compute the
object header size and it is immutable.
This patch also renames InstanceSize to InstanceSizeInWords where
the instance size is represented in words.

The logger for perf does not support relocating code objects so as a result we
disable code space compacting to make sure code does not move. However, a
a CodeMove event may still happen if a BytecodeArray object moves, which isn't
relevant to the perf jit support so we can ignore it.
