[turbofan] Unify referencing of stack slots
Previously, it was not possible to specify StackSlotOperands for all
slots in both the caller and callee stacks. Specifically, the region
of the callee's stack including the saved return address, frame
pointer, function pointer and context pointer could not be addressed
by the register allocator/gap resolver.
In preparation for better tail call support, which will use the gap
resolver to reconcile outgoing parameters, this change makes it
possible to address all slots on the stack, because slots in the
previously inaccessible dead zone may become parameter slots for
outgoing tail calls. All caller stack slots are accessible as they
were before, with slot -1 corresponding to the last stack
parameter. Stack slot indices >= 0 access the callee stack, with slot
0 corresponding to the callee's saved return address, 1 corresponding
to the saved frame pointer, 2 corresponding to the current function
context, 3 corresponding to the frame marker/JSFunction, and slots 4
and above corresponding to spill slots.
The following changes were specifically needed:
* Frame has been changed to explicitly manage three areas of the
callee frame, the fixed header, the spill slot area, and the
callee-saved register area.
* Conversions from stack slot indices to fp offsets all now go through
a common bottleneck: OptimizedFrame::StackSlotOffsetRelativeToFp
* The generation of deoptimization translation tables has been changed
to support the new stack slot indexing scheme. Crankshaft, which
doesn't support the new slot numbering in its register allocator,
must adapt the indexes when creating translation tables.
* Callee-saved parameters are now kept below spill slots, not above,
to support saving only the optimal set of used registers, which is
only known after register allocation is finished and spill slots
have been allocated.

Filter out slot buffer slots, that point to SMIs in dead objects.
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.

[runtime] Simplify CHECK_OBJECT_COERCIBLE.
Don't use IS_NULL_OR_UNDEFINED() for CHECK_OBJECT_COERCIBLE() because it
will also return true for undetectable objects, but use IS_NULL() and
IS_UNDEFINED() directly, which will only return true for null or
undefined (which matches the semantics of the abstract operation
CheckObjectCoercible).
