    [ic] Handle JSArray::length in CodeStubAssembler::CallGetterIfAccessor. · 0322be81
    Benedikt Meurer authored
    When accessing JSArray::length property from GenericPropertyLoad
    (i.e. via a megamorphic KEYED_LOAD_IC), we'd always go to the runtime
    at this point, because the CallGetterIfAccessor method didn't support
    AccessorInfos at all. Now there's initial support for JSArray::length,
    which reduces the number of %KeyedGetProperty calls we see in the
    Speedometer/EmberJS test by 5000.
