Revert of [typedarrays] move %TypedArray%.prototype.copyWithin to C++ (patchset #6 id:100001 of https://codereview.chromium.org/2671233002/ ) Reason for revert: Due to security issue described in review thread. Original issue's description: > [typedarrays] move %TypedArray%.prototype.copyWithin to C++ > > - Removes shared InnerArrayCopyWithin JS builtin from src/js/array.js > - Implements %TypedArray%.prototype.copyWithin as a C++ builtin, which > relies on std::memmove rather than accessing individual eleements. > - Fixes the case where copyWithin is invoked on a TypedArray with a > detached buffer. > - Add tests to ensure that +/-Infinity (for all 3 parameters) is handled correctly by the > algorithm > > The C++ version gets through the benchmark more than 25000 times as > quickly as the JS implementation. > > BUG=v8:5925, v8:5929, v8:4648 > R=cbruni@chromium.org, adamk@chromium.org, littledan@chromium.org > > Review-Url: https://codereview.chromium.org/2671233002 > Cr-Commit-Position: refs/heads/master@{#42975} > Committed: https://chromium.googlesource.com/v8/v8/+/0f1c626d556cbf84b0e572635eb803729f88cbb3 TBR=cbruni@chromium.org,adamk@chromium.org,bmeurer@chromium.org,cwhan.tunz@gmail.com,caitp@igalia.com # Not skipping CQ checks because original CL landed more than 1 days ago.
