          Priority: P2

Test cases

See attached TC.

The special [[Get]]/[[Put]] defined in ES5.1 §8.7 calls accessors with the primitive value as thisArg; in the non-strict accessor case §10.4.3 calls ToObject on thisArg before entering the function code, whereas in the strict accessor case thisArg is passed through untouched (i.e., as a primitive).

Currently SM (730632), JSC, and Carakan (CORE-44789) all always wrap, V8 never does (about to be reported).
