ClusterFuzz test is triggering assertions for dead code. This fix issues
HDeoptimize instruction when it finds out that the compare instruction

The problem is that conditions are evaluated before configuration inheritance is resolved, so we can't just define a configuration like this:

'Optdebug': {
  'inherits_from': ['Debug'],
  'variables': {
    'v8_optimized_debug': 2,
  }
}

Instead, we have to put the different settings depending on the optimization level into separate configurations, and use conditions inside the concrete configurations to inherit from the correct base class.

Common settings go in the base configuration DebugBaseCommon, and v8_optimized_debug dependent settings go into DebugBase{0,1,2}

The new Debug configuration inherits from DebugBaseCommon and DebugBase<(v8_optimized_debug), while the new configuration Optdebug inherits from DebugBaseCommon and DebugBase2.

We should check for overflow for each inlined property getter;
otherwise, we can get an overflow from inlining property getter while
still having pending overflow exception from some previous inlined
getter (in the same polymorphic access).

The simulator can trace to a specified stream, typically stderr or
stdout. However, several messages (such as ASM_LOCATIONs) were printed
only to stdout. As a result, they often ended up out of order with
respect to the instruction trace. This patch causes all simulator output
to go to the same stream.

Some heap pointer's embedded in optimized code are considered weak. Ensure
that we don't mark them during GC of the ConstantPoolArray.  Also, embed
length metadata in a bitfield, reducing the ConstantPoolArray header size from
five words to two.
