After reducing the noise in jsfunfuzz output (1378177), we need to make sure that the builders pick up the latest version of this repository. Currently, because the builders haven't downloaded the repository after the change landed, they're still using the previous version of the jsfunfuzz runner.

The SFI's flags can be changed by the mutator while the concurrent marker is checking the flags for bytecode flushing. None of the flag bits checked for bytecode flushing are changed, however since they are in an int32 field TSAN will complain if any of the other flags are changed while reading from another flag. Fix this by making the flags use the RELAXED_INT32_ACCESSORS.

This CL introduces our own minimal SmallVector implementation and uses it in several places (more might follow). I measured that in the majority of cases, these vectors are quite small (<= 8 elements), so we will avoid any heap allocation in those cases.

This CL implements the global.get and global.set instruction for anyref globals. This includes: * Properly decode anyref globals. * Add a FixedArray to WasmInstanceObject to store anyref globals. * Initialize the FixedArray. * Generate code for global.get and global set. This CL does not allow to import globals yet.

The parser object can now be created on a worker thread, therefore we shouldn't access global FLAGs during the constructor. Instead move them to the ParseInfo constructor and set the parser fields based on these. Also avoid accessing always_opt flags in bytecode-flags - instead accessing it in ParseInfo and propagating to the bytecode generator.

Since it's explicit what we're tracking, we can immediately throw errors in certain cases, and ignore irrelevant errors. We don't need to use the classifier itself to track "let let", since we know whether we're parsing a "let". Errors that were previously (almost) always accumulated are now immediately pushed to the scopes that care (parameter initialization errors). This CL drops avoiding allocation of classified errors, at least for now, but that doesn't affect performance anymore since we don't aggressively blacklist anymore. Classified errors are even less likely with the more precise approach. ParseAssignmentExpression doesn't introduce its own scope immediately, but reuses the outer scope. Rather than using full ExpressionClassifiers + Accumulate to separate expressions/patterns from each other while keeping track of the overall error state, this now uses an explicit AccumulationScope. When we parse (async) arrow functions we introduce new scopes that track that they may be (async) arrow functions. We track StrictModeFormal parameters in 2 different ways if it isn't immediately certain that it is a strict-mode formal error: Either directly on the (Pre)ParserFormalParameters, or on the NextArrowFunctionInfo in the case we're not yet certain that we'll have an arrow function. In the latter case we don't have a FormalParameter object yet, and we'll copy it over once we know we're parsing an arrow function. The latter works because it's not allowed to change strictness of a function with non-simple parameters.
