MIPS: EmitCreateIteratorResult loads map from function's context.

Port r24987 (cfc4713)

Original commit message:
Caching or serialization can cause full-codegen output to be shared
between contexts.  CreateIteratorResult, however, was doing the wrong
thing by creating results with the map that was current when the code
was generated.  Instead, we should chase pointers to load the right map
from the function's context.
