Some includes in log.h were only needed by log.cc so move them there. Some were not needed at all, so remove them completely. Drive-by cleanup FunctionEvent(), which was never called without args for the last parameters which had default values.

The main fix is to ensure that the recently allocated object is marked black in StressMarkingObserver::Step. Otherwise, the concurrent marker can observe an uninitialized white object in the old generation. This patch also removes the --black-allocation flag.

The test was originally testing the max string length limit, but due to refactoring of Array.join started consuming too much memory, resulting in OOMs on TSAN builds. The new implementation still checks for the limit, while reducing the memory consumption drastically.

This CL enables the pre-processing step of copying from the prototype chain for JSArrays. Previously, this was done for everything BUT JSArrays.

In wasm code, we sometimes see the pattern <some 64 bit expression> i32.wrap/i64 i32.load where we generate an instruction to extend the 32 bit offset into a zero extended 64 bit value for the actual load. However, the preceeding truncate already yields a zero extended 32 bit value, so the extra instruction is not needed. Even more, it might get in the way of munching more computation into the final load. This change adds information about the zero extending behavior to the existing optimization that avoids the zero extension.

The decision as to whether to optimize an IIFE as oneshot depends on whether it's outer scope is the script scope. During lazy compile, we might have discarded scopes which don't need a context between the IIFE and the script scope, which means we might treat an IIFE as oneshot, even though initial eager compile treated it as non-oneshot. Both bytecode flushing and lazy source positions rely on us generating the same bytecode during lazy compile as eager compile, so we move the decision into the parser where it happens once and is then stored in the SFI for any future lazy compiles.

Currently the memory reducer is activated only after the first mark- compact GC, which triggered after the old generation reaches 8 MB. That threshold is too large for mobile. This patch adds a heuristic to activate the memory reducer if the old generation expands by more than 1 MB after the bootstrap.

This current fails, since {mmap} fails with EINVAL for empty mappings. The destructor already has special handling for a {nullptr} mapping, so we can just use {nullptr} for empty files. We get a similar error on windows, and can fix it the same way. On order to make presubmit checks happy, we have to skip copyright checking and checking for terminating newlines for empty files.

This removes the unused "argument count" field from the safepoint table as the field was unused by now and always contained the value zero. Also note that associating a callee's argument count with the call-site is not compatible with tail-call support. When tail-calling a function with a different number of arguments, the information associated with the call-site becomes stale. The number of arguments is a property of the callee, not of the call-site in the caller. For this reason the field in question is not usable to support reference types in function arguments (at least when tail-calls are also supported).
