Introduce common bottleneck for all incremental marking step
invocations from a task context. This will later be used to move
code out of IncrementalMarking::Step.

This is a reland of https://crrev.com/c/3822682. This CL now always

The external pointer table is already to some degree self-compacting: as
the freelist is sorted in ascending order, free entries at the start of
the table should quickly fill up. However, any live entry at the end of
the table makes it impossible to shrink the table, thereby causing
higher memory consumption. To solve this, this CL implements a simple
table compaction algorithm, used when the freelist has become
sufficiently large (currently >= 10% of the table capacity):
 - The goal of the algorithm is to shrink the table by freelist_size/2
   entries at the end of compaction (during sweeping).
 - At the start of the marking phase, the compaction area is computed as
   roughly [capacity - freelist_size/2, capacity).
 - When an entry is marked as alive that lies inside the compaction
   area, a new "relocation entry" is allocated for it from the freelist
   and the address of the handle for that entry is stored in that entry.
   If there are no more free entries before the compaction area,
   compaction is aborted. This is expected to happen rarely and is
   logged into a histogram.
 - During sweeping, all relocation entries are "resolved": the content
   of the old entry is copied into the new entry and the handle is
   updated to point to the new entry.
 - Finally, the table is shrunk and the last initial_freelist_size/2
   entries are decommitted.

See also the comments in the ExternalPointerTable class for more details.

Consider the function:

function foo() {
  debugger;
  let y = 1;
}

V8 will elide the hole initialization for 'y'. When we pause at the
debugger statement, then 'y' evaluates to 'undefined'.

This CL fixes this in the ScopeIterator. When we encounter local
variables with an `undefined` value we check the static scope
information if we are stopped *before* the variable's initializer.
If yes, then we are in the variable's TDZ and report
"value unavailable".

Drive-by: Mark `GetSourcePosition()` as `const` to make it available
in the visitor method.

This CL replaces the AllocateExternalPointerEntries methods with
per-field init_##fieldname methods for every external pointer field.
These now initialize the field by allocating the external pointer table
entry for it and also set the initial value. This saves one memory write
in the typical case (what used to be AllocateExternalPointerEntries
followed by a set_##fieldname) and removes some code that can be
factored out into the (DECL_)EXTERNAL_POINTER_ACCESSORS macro.

TotalDurationNanoseconds previously return a double to represent the
total duration nanoseconds, but the value could be easily bigger than
the precise value a double can represent. A double can precisely
represent integer to 2^53, which is only about 104 days if that value
is nanoseconds. So we need to change the return type to BigInt.

This CL builds upon https://crrev.com/c/3284887 (and partly reverts it).

Class literals are a bit iffy when it comes to source position and
debugging. Mainly the debugger assumes the following invariant:
When we are paused inside a class scope, then we expect the class's
BlockContext to be pushed already. On the other hand, when we are
paused outside a class scope in a function, we don't expect to find
the class's BlockContext.

The problem is that there are cases where we can either pause
"inside" or "outside" the class scope. E.g.:

  * `var x = class {};` will break on `class` which is inside
    the class scope, so we expect the BlockContext to be pushed

  * `new class x {};` will break on `new` which is outside the
    class scope, so we expect the BlockContext to not be pushed
    yet.

The issue with the fix in https://crrev.com/c/3284887 is that it
adjusted the break position for the bytecode of class literals to
ALWAYS be after the BlockContext is pushed. This breaks the
second example above. We need to tighten the fix a bit and only
defer the break position if the "current source position" is
inside the class's scope. This way we always guarantee that the
BlockContext is pushed or not, depending if the source position
that corresponds to the break position is inside or outside the
class's scope.

Note 1: The CL updates a lot of the bytecode expectations. This
is because the class literals are often the first statement in
the snippet so we don't need to defer the break position.

Note 2: We add a mirrored debugger test to the inspector test so
the fuzzer can have some more fun.

address first using the root register and only then loading its value.
