The past re-factoring inadvertently increased memory consumption for AstConsString. This implements a micro-optimization to revert and slightly improve beyond the original state. Example, Zone size for parsing closure.js: - 20,999,848 B (before refactoring) - 21,651,056 B (after refactoring patch; 3.1% regression) - 20,641,320 B (after this CL; 1.7% improvement over original) (Reason: ZoneLinkedList requires 4 pointers to support the std::list functionality (Zone*, head/tail ptr, payload ptr). But since we only append and iterate in order and have the Zone* available in the context, a super simple linked list (value + next ptr) saves a bit of memory, especially for the common case of having 0 or 1 string segments.)

The unwinding information we emit wrongly encodes code locations as relative offsets. If we look at the .eh_frame section of shared object generated by "perf inject" using "objdump -g": ~~~ 00000000 0000000000000018 00000000 CIE (snip) 0000001c 0000000000000028 00000020 FDE cie=00000000 pc=fffffffffffffee8..00000000000017f8 (snip) 00000048 ZERO terminator ~~~ We can see the range that the FDE entry covers is incorrect, it should point to where the .text section is, at address 0x40 on a 64-bit architecture. The reason for this was that the PerfJitLogger logs a code size that is different from the one we've used when encoding the unwinding information. The logger will ignore the safepoint table while the unwinding info assumes it is part of the code.

Make sure that we call the destructors on all embedded object by replacing the WasmInterpreterInternals::Delete method by an actual destructor. This way, the compiler automatically calls destructors on all embedded objects, in particular the IdentityMap in the CodeMap. This change also requires to release managed objects *before* tearing down the heap, because the wasm interpreter, referenced via Managed<>, contains global handles. When those are destroyed, the isolate still needs to be intact. Drive-by: Fix include guard in managed.h.

For sloppy arguments in functions with declared formal parameters, the apply with arguments optimization in TurboFan wouldn't kick in currently, because so far there was no guard to see if using the arguments from the stack or the frame state is safe. One easy to check guard here is to just check that there's no observable side-effect between the actual arguments creation and the call to apply.
