Reviewers: danno, Description: Improve polymorphic loads on single slots.
If all property lookups for a polymorphic load actually result in the same field index under all maps, we can actually emit a monomorphic load that is guarded by a map check that verifies that the actual map is in the set of handled maps. This also allows GVN to get rid of redundant such map checks.
