Reviewers: Michael Starzinger,
Description:
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.
