JSObject::UnregisterPrototypeUser relies on the index of the weak
fixed array entry not to change.
See commit 1e65e2018.
There is no bug currently, because we would only re-allocate if there is no empty slot left. In which case there is no actual compaction going on during re-allocation.

This mainly changes how we share ToBoolean, ToNumber and ToString between
native scripts. Instead of putting them on the js builtins object, we now
explicitly export and import those functions.
I also had to change the import/export mechanism slightly. Previously,
exports and imports are hooked up after all native scripts have been
executed. This means that imported functions cannot be called at the time
the native script is executed.
However, since ToBoolean (and also e.g. ObjectDefineProperties) is called
in v8natives.js, I changed the mechanism so that exports from previous
native scripts (runtime.js for ToBoolean) is imported immediately and can
be called.

port f4c079d450 (r30107).
original commit message:
There's no need to have one InstanceType per SIMD primitive type (this
will not scale long-term). Also reduce the amount of code duplication
and make it more robust wrt adding new SIMD types.

The ES6 spec for this function declares that ToLength
should only be called once. We were evaluating it multiple
times, so if length was an object with a valueOf method,
we could see effects take place multiple times.

Don't use exit(), use Shell::Exit() (which calls _exit() instead). This won't
run C++ static destructors, atexit() functions, etc., which can occasionally
cause flaky failures.

This warns about include directives of inline headers within normal
header files. Note that this warning should not close the tree or
prevent the CQ from landing the patch.

This CL us a pure refactoring that makes an empty compilation unit
including just "heap.h" but not "objects-inl.h" compile without
warnings or errors. This is needed to further reduce the header
dependency tangle.

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.

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.
