This CL implements the functionality of SafeRemoveArrayHoles (JS), which is used as a pre-processing step for sorting, in a runtime function. SafeRemoveArrayHoles is a generic fallback, when an existing runtime function fails to remove holes/move undefineds to the end of an array. This CL extends the existing runtime function to also support JSProxy objects, and objects where indices have accessors.
