Reviewers: Mads Ager,

Description:
Add "has fast elements" bit to maps and use it in inlined keyed loads.

A potential issue with this change is creating lots of maps when
objects flip between fast/slow elements modes.  We could add special
transitions to avoid this.  Yet testing this on our benchmarks, gmail,
and wave seems to indicate that this is not a real problem.
