This CL removes all uses of InnerAllocate (except memento allocations) and replace with non-folded allocations. The change is based on the fact that 1. Those InnerAllocates are not guarded by --allocation-folding flag. 2. Hopefully the MemoryOptimizer can handle the folding and no performance regression will happen. Two special versions of InnerAllocate is still kept: * One for memento allocations (renamed to InnerAllocateMemento). * One for AllocateUninitializedJSArrayWithElements (renamed to InnerAllocateElements).

The split between "Complete" methods and "Validate" methods is subtle and undocumented. The "Complete" methods are only used in places where we know that the function is valid anyway: Printing wasm code and getting stack effects of an instruction (for the interpreter). Both are also not performance critical. Hence this CL merges the "Complete" methods in the respective "Validate" methods and just call the latter instead of the former.

So far, units compiled with TurboFan were published one-by-one as soon as they were ready, which reduces the latency until the faster code is available. However, especially when write-protecting code with mprotect, this yielded a lot of page protection switches, which incurs syscall and lock contention overhead. Thus, https://crrev.com/c/2922114 already introduced TurboFan batching when using write-protection. During experiments, we found this could even be beneficial in the default configuration, i.e., without write-protection enabled. This CL changes to always do the publishing in batches. This choice should be revisited once the tier-up strategy changes, e.g., with lazy compilation or dynamic tier-up.

AllocationSites are strongly rooted in various places. AllocationMementos, small heap objects immediately behind the objects which AllocationSites tracks, are purposely left unrooted. They do however, point to AllocationSites. This leads to a situation where an AllocationSite may no longer be seen to have strong roots at gc time, and yet new space is still repleat with AllocationMementos which point to it. The GC recognizes this, and marks the AllocationSite as a "zombie," that is, an object which should be kept alive for one more GC cycle because of the existence of those mementos which point to it.
