Makes the following modifications to the interpreter builtins and
InterpreterAssembler:
 - Adds an accumulator register and initializes it to undefined()
 - Adds a register file pointer register and use it instead of FramePointer to
   access registers
 - Modifies builtin to support functions with 0 regiters in the register file
 - Modifies builtin to Call rather than TailCall to first bytecode handler.

The following situation may happen which reproduces this bug:
(1) We allocate JSObject A on an evacuation candidate.
(2) We allocate JSObject B on a non-evacuation candidate.
(3) Incremental marking starts and marks object A and B.
(4) We create a reference from B.field = A; which records the slot B.field since A is on an evacuation candidate.
(5) After that we write a SMI into B.field.
(6) After that B goes into dictionary mode and shrinks its original size. B.field is now outside of the JSObject, i.e B.field is in memory that will be freed by the sweeper threads.
(7) GC is triggered.
(8) BUG: Slots buffer filtering walks over the slots buffer, SMIs are not filtered out because we assumed that SMIs are just ignored when the slots get updated later. However, recorded SMI slots of dead objects may be overwritten by double values at evacuation time.
(9) During evacuation, a heap number that looks like a valid pointer is moved over B.field.
(10) The slots buffer is scanned for updates, follows B.field since it looks like a pointer (the double value looks like a pointer), and crashes.

This removes the dependency of the MarkingDeque on the underlying
collector by moving out the live bytes accounting and object color
mutations into a wrapper. The MarkingDeque can now be split into a

Add Object::StrictEquals to unify the implementation of strict equality
comparison in the runtime and the api (the api was already missing a
case for SIMD).  Now we (almost) have a single bottleneck for strict
equality, we just need to reduce the amount of unnecessary complexity
for the code stub.

Previously, all extras were "experimental" and left out of the snapshot. This
patch moves them to the snapshot, so now all extras are non-experimental. A
future patch will re-introduce experimental extras as part of the linked bug.
