The VM state is a property of the isolate, not the CPU profiler.
Having to create a v8::CpuProfiler instance in order to change
the property is somewhat inefficient.

See https://github.com/nodejs/node/issues/18039 and
https://github.com/nodejs/node/pull/18534 for context.

The idea of GetUnaryOpTargetRegister and GetBinaryOpTargetRegister is
to reuse the register of one of the operands instead of using an
separate third one, because we can often generate better code if the
destination register matches the src or lhs.
This was implemented by looking at the top or the first two stack
entries, and using one of their registers if there is only one use.
Instead of doing that we can also just pop them and then later check
whether this was the only use. This makes the code smaller, more
readable and probably faster.

The optimized code for %ArrayIteratorPrototype%.next for holey arrays
was wrong, since it would first store the [[NextIndex]] and then check
whether it hit a hole. However in that case TurboFan doesn't have any
point to deoptimize to, so we need to perform the side-effecting stores
only after all checks are done.

Original Commit Message:

    Implement in-place weak reference handling in GC.

    Turn FeedbackVector::optimized_code_or_smi into an in-place weak reference (this
    is the only in-place weak reference at this point).

    (See bug for design doc.)

There must not be both an allocating function call and a handle deref
in the list of arguments to a call. Depending on the evaluation order
that the C++ compiler chooses, the deref could happen before the call
and the resulting raw pointer be invalidated by the GC.

I initially left them out because I thought they are harder to
implement than the other float binops, but it turns out it is actually
just the same.

This patch moves the has_braces_ bool to the bit_field_, and moves
function_literal_id_ into the freed-up slack space. This saves
4 bytes on 32-bit platforms and 8 bytes on 64-bit.
