We constantly fight against scrambled output with --print-wasm-code and other flags. Passing --single-threaded only partially mitigates this, because there could still be multiple isolates (e.g. Workers), and we sometimes failed to really execute in a single thread if that flag was set. Hence this CL solves the problem in a more fundamental way: Whenever a {StdoutStream} is constructed, it implicitly takes a global recursive mutex. The recursive mutex is needed because we still have some printing methods that don't take a stream as parameter, and instead create their own instance of {StdoutStream}, which should not crash of course. The overhead of taking a mutex should be acceptable, since output to stdout mostly happens if special tracing flags have been passed, and is slow anyway. This CL ensures that the {StdoutStream} is used at least for --print-code, --print-wasm-code, and --trace-turbo-graph. More flags can later be ported on demand. The {JSHeapBroker} class was modified to not contain a {StdoutStream}, but instead create one on demand.

When the intention is to handle every case, *and* when we can be reasonably sure that no invalid enum values will occur (e.g. from reading untrusted data), then we shouldn't have a "default:" case in a switch statement so that the compiler will warn us when a case is missing.

This builtin essentially acts like InterpreterAssembler::Construct. It collects full feedback, then tail-calls either the array constructor or the construct builtin. For now, it is only used in generic lowering, if the --turbo-nci flag is passed. One of the next steps will be to measure performance impact of feedback collection. If minimal, we may want to enable it unconditionally in generic lowering.

For debugging (either with --print-wasm-code, or inspecting the current code object in a debugger) it's helpful to also see the debug side table, if available. This CL adds print support for that, and uses it when printing wasm code, and after generating a new debug side table.

Changes: Cleanup: - Make sure read_value_type has the same interface as other read_* functions, i.e., returns the decoded value and writes the consumed length into a pointer. - DecodeLocals is now an instance method. - DecodeLocals should fail when given a wrong number of locals. Add tests to catch that. - Fix a buggy test. Refactoring in preparation of introducing the 'let' instruction as per [wasm-gc]: - DecodeLocals does not consume any input and can start from any pc. - DecodeLocals gives the option of not appending the decoded locals to local_types_. - Separate locals initialization from signature.
