Support StringLength in hydrogen (similar to ArrayLength).

To avoid deopts a few extra changes were needed:

o Enable megamorphic state for special property loads on
  primitives. We used to flip between monomorphic stubs.
o Extract pure string (no string wrapper support) version of the
  string length stub.
