Concurrent sparkplug adds functions to batches and sends those batches off for compilation, but doesn't note what functions are currently compiling. This means that we can spawn multiple compilation jobs for a function, most of which will be throw away. Add a bit to SharedFunctionInfo to note whether concurrent compilation has been started for it.

A few more fixes for visiting bytecodes that are known to be dead: * Change JumpLoop dead frame merging to remove the loop predecessor, by moving the loop predecessor to be the last in the list and allowing it to be dropped the same way as other predecessors. * Remove the bytecode walk in EmitUnconditionalDeopt, opting instead to check for null current_block in the real bytecode visitor. This allows us to handle the case where the start of a basic block is dead, but there's no fallthrough into it, so it wouldn't be visited by the loop in EmitUnconditionalDeopt.

Currently, young generation assumes that all the on-heap pointers are compressed, which is currently not the case due to the backing-store pointers in Blink. Fixing collections to have Member<> is not easy, because the inlined collections may have the semantics that backing_pointer_ == inlined_buffer_; where the inlined_buffer_ can be off-heap (e.g. on stack). The CL introduces another type of barrier specifically for uncompressed pointers. The followup is to use that barrier from Blink.

Add a new --wasm-max-module-size flag to replace the unused and more specific --experimental-wasm-allow-huge-modules flag. The new flag can be used in fuzzers to reduce the maximum allowed module size, avoiding OOM on some systems (like 32-bit ASan builds).

When profiling V8 code generated with snapshot using ETW, there is a huge difference enabling system instrumentation. This is because, for populating the ETW tracing (when --interpreted-frames-native-stack is enabled), we need the scripts line ends. But these are only generated if log functions are enabled. To prevent the problem, this CL also initializes script line ends for the case interpreted frames native stacks are enabled.

This CL extends the live edit mechanism to allow editing the function that is currently on top of the stack, as long as that call frame is the only activation of that function. The CL changes how we look for functions on the current JS stack: Instead of starting at thread_local_top we start at the frame we are currently paused in. This is possible since there can not be any JavaScript frames above the current "break frame", only C++ frames which are not relevant for live edit. If the edited script modifes the top-most function, the inspector will trigger a restart of that call frame. That is why we check if we can actually restart the function and only allow the live edit to go through if that is the case. Note that this CL also adds a kill switch in the form of a runtime flag for this feature, in case we need to pull the plug and disable this feature again via back-merge.

Already after enabling Liftoff, the name did not match the semantics any more. The callback was called after top-tier finished, not after initial compilation of the module finished. With dynamic tiering, the name is even less fitting. This CL renames the "OnModuleCompiled" callback in the API to "MoreFunctionsCanBeSerialized", which makes it more obvious what the API should be used for. It also internally renames all related typedefs and methods accordingly. One call of the callback in the streaming decoder was already wrong before this CL and is being removed.

Use the field index to look up the descriptor for double fields, and add a dependency on them. Drive-by, fix store field optimisation to only emit the optimised direct store for tagged fields, so that we don't accidentally insert HeapNumbers into double fields (making them mutable).
