Added %_HeapObjectGetMap and %_MapGetInstanceType intrinsics.

Added %_HeapObjectGetMap and %_MapGetInstanceType intrinsics.

These are needed (among other things) for a TurboFan-generated
StringAddStub. Furthermore, they can be used to nuke the overly
complex %_IsInstanceType intrisic, it's completely expressible in
JavaScript now, but that will be done in a separate CL.

Alpha-sorted things a bit on the way to ease navigation.

I never understood the "Inline" prefix in all of these methods. Is there a
particular reason the new ones don't have the prefix? Could we just
s/ReduceInline/Reduce/ for all methods?

Neither do I.

I just forgot it. :-)
