Add a struct CodeReference that can be stack allocated to pass a reference to either an on-heap code object or off-heap WasmCode object in a gc safe manner. The struct also provides a common interface such that code can be written independently of the kind of code object it references.

It was supposed to add some randomness to the order of generated code objects, but it is totally unclear whether this is working, needed or helpful.

Looking up line numbers with the JITLineInfoTable would sometimes give wrong answers. Fix these bugs and add a cctest for this data structure. Also do some cleanup while we're here like inlining the (empty) constructor and destructor and removing the empty() method which is only used unnecessarily anyway, to make the contract of GetSourceLineNumber a bit clearer. Also rename the data structure to SourcePositionTable, because it doesn't just provide info for JIT code, but also bytecode, and 'Info' is pretty ambiguous.

Memory size, mask and function table size are 32-bit values in wasm. There is no relation to pointer size. Hence, replace uintptr_t by uint32_t. These fields are already being loaded as uint32_t in wasm-compiler.cc, causing problems on big endian systems.

This is to fix an assertion failure in formatToParts when Chinese calendar is specified with 'u-ca-chinese'. See https://github.com/tc39/ecma402/issues/225 . This CL is a temporary work-around to get v8 match the spec in terms of the external behavior, but it's not taking the steps in the spec, yet. Moreover, the spec may have to be revised as to how to pick the best match pattern when the default calendar for a locale is different from the calendar specified via 'u-ca'. How to handle 'related year' part also needs to be specified.

Port ada64b58 Original Commit Message: Before Turbofan/Ignition it was possible to use external profilers to sample running V8/Node.js processes and generate reports/FlameGraphs from that. It's still possible to do so, but non-optimized JavaScript functions appear in the stack as InterpreterEntryTrampoline. This commit adds a runtime flag which makes interpreted frames visible on the process' native stack as distinguishable functions, making the sampled data gathered by external profilers such as Linux perf and DTrace more useful.

ValueDeserializer::ReadWasmModule does not call API functions, therefore there can be no scheduled_exceptions, and therefore we do not have to translate scheduled_exceptions to pending_exceptions. On the contrary, there can be pending_exceptions, which causes the call to RETURN_EXCEPTION_IF_SCHEDULED_EXCEPTION to crash. This CL fixes a crash in a layout test which was caused by another CL (https://crrev.com/c/975547).
