Port 3cad6bf5 Original Commit Message: This is a reland of c7c47c68. This makes TSAN happy in addition to: Previously I presumed that the context read from a frame in the profiler was a valid context. Turns out that on non-intel we're not guaranteed that the frame is properly set up. In the case we looked at, the profiler took a sample right before writing the frame marker indicating a builtin frame, causing the "context" pointer from that frame to be a bytecode array. Since we'll read random garbage on the stack as a possible context pointer, I made the code reading the native context from it a little more defensive. Bug: v8:9860 Tbr: ulan@chromium.org, neis@chromium.org, ishell@chromium.org Original change's description: > [runtime] Move Context::native_context to the map > > Remove the native context slot from contexts by making context maps > native-context-specific.

Currently, RegExpResult builds match indices lazily using data stored in hidden internal fields on the result object itself. Unfortunately, if an internal field is deleted, it can cause these hidden fields to migrate to a dictionary, making indexed lookup unsafe. This CL forces slow but safe lookup for these fields when lazily building indices.

The new regexp_backtracks / V8.RegExpBacktracks counter tracks the number of backtracks performed per regexp execution. The results can help us prioritize related work. Note that we only count backtracks in the interpreter. Jitted code is ignored. With our current regexp tiering strategy, that means we count backtracks only in the first execution of each regexp.

This CL ensures that recorded slots are either in the sweeping or the old-to-new remembered set after mark-compact depending on whether the page was already swept or not. All pages that are swept during the evacuation phase also have their remembered sets merged. is_local() is renamed to is_compaction_space() and non-virtual. The PagedSpace now not only knows whether it is a compaction space or not but also for which collection through the compaction_space_kind_ field. This allows RefillFreeList to merge the remembered sets immediately also for the mark-compact collection.
