mstarzinger@chromium.org 5bca664574 MIPS: Improve polymorphic loads on single slots. 
Port r11132 (91bdad6108).

Original commit message:

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.
