adamk@chromium.org 5f1ae66d56 Narrow cases where Sparse/Smart versions of Array methods are used ... Added a new %HasComplexElements runtime function (meaning elements that are non-writable, non-configurable, or have getters and setters) and use it in UseSparseVariant to filter out cases where the sparse optimizations can cause V8 to fall out of spec compliance. Renamed SmartMove/SmartSlice to SparseMove/SparseSlice and guarded them with the new and improved UseSparseVariant. These two changes combine let us pass nearly every test in bug-2615.js, as well as fixing reverse and join on sparse arrays. Note that there are various test changes in this patch that correct existing tests to match the correct-by-spec behavior. This patch depends on https://codereview.chromium.org/666883009, which better-aligns the behavior of SmartMove with SimpleMove.
