Move ScopeInfo allocation out of DeclarationScope::Analyse and do it later in the compile when finalizing unoptimized code generation. This is to enable scope analysis to be done without heap allocation so it could run off-thread.

We currently have a fixed limit of 256 characters for error messages generated in the decoder. However, we sometimes embed names in it, which makes it easy to generate a crash by using long names (e.g. for exports) in invalid wasm modules. This CL fixes this by switching to a stream based interface, allowing to pass arbitrary objects to be printed. With this interface, we can easily limit the length of output later.

This switches the "code entry" field on JSFunction to no longer be an inner pointer into a Code object (i.e. to the start of the instruction stream), but a properly tagged pointer instead. Motivation behind this is the ability to treat this field regularly as part of escape analysis in the optimizing compiler. Also simplifies the object visitation for JSFunction objects.

The barrier assumed that the number of tasks is fixed. However, we cannot rely on that because other tasks might take up threads. In the ein thend this would result in the Scavenge task being (rightfully) cancelled. The barrier now assumes no tasks in the beginning and relies on the fact that reaching the barrier means that no global work is left. Tasks that lag behing will just observe the barrier being in its end state.

Properly hook up the (existing) IC slots for the CallWithSpread and ConstructWithSpread bytecodes, and change the interpreter to collect feedback (call counts and regular target function feedback) for those. There's no integration with the Array constructor yet, since that requires some yak shaving to thread through the AllocationSite to the Array constructor stub. Once we have a solution for that, we can also remove the current code duplication in the Call/Construct IC logic. Also properly hook up the newly available feedback in TurboFan. This will fix not only the missing target feedback, but more importantly the tear-up decisions for optimization are correct now in the presence of spread calls, and even more importantly the inlining heurstic has proper call frequencies for those. Some follow-up changes will be necessary to make sure we use the feedback even for corner cases that aren't handled properly yet. Also we should consider collecting feedback about the map of the spread at some point to be able to always inline the spread calls.
