    [Interpreter] Add ForInPrepare runtime function which returns a ObjectTriple. · 84f8a506
    rmcilroy authored
    Adds a ForInPrepare Runtime function which returns a triple of
    cache_type, cache_array and cache_length.
    
    This requires adding support to CEntryStub to call runtime functions
    which return a ObjectTriple - a struct containing three Object*
    pointers. Also did some cleanup of the x64 CEntryStub to avoid
    replicated code.
    
    Replaces the interpreter's use of the ad-hock InterpreterForInPrepare
    Runtime function with ForInPrepare in preparation for fixing deopt in
    BytecodeGraphBuilder for ForIn (which will be done in a followup CL).
