Overview: - Change basic type hierarchy to split Tagged into StrongTagged (= Object) and and WeakHeapObject. This enables to emit the right CSA types (Object, MaybeObject). - The new Weak<T> type encodes a possibly cleared weak bit pattern that points to type T if it's not cleared. - Make TNode<Object> a subtype of TNode<MaybeObject> so that the generated code compiles on the C++ side. Drive-by change: simplify a few CSA helpers by using MaybeObject as a common supertype of MaybeObject and Object. - Port CreateObjectWithoutProperties and LoadMapPrototypeInfo.

Live sets represent sets of live virtual registers at block entry and exit points. They are usually sparsely populated; for example, a sample taken from Octane2 shows 80% of sampled live sets with a fill ratio of 10% or less. Prior to this CL, live sets were implemented as a statically-sized bit vector. This is fine for low-ish virtual register counts, but becomes wasteful at higher numbers. This CL attempts to address this issue through an adaptive implementation. Small live sets remain bit vectors, while larger sets switch to a PersistentMap-based implementation. PersistentMap has very memory-efficient add/remove/copy operations. Of course, with adaptive data structures we enter the territory of parameter fiddling. In this case, two parameters are used: kMaxSmallSetSize controls when to switch implementations, and kMaxDeletionsBeforePrune controls when pruning (= managing the # of deleted entries in the map) sets in. On the (degenerate) test case from the linked bug, the register allocation zone shrinks from 1008MB to 475MB. For more realistic cases I expect savings on the order of 10s of KB.

All the data types defined under ArgValue are 8 bytes expect "bool as_bool". When casting to <uint64_t> under "tracing/trace-event.h", boolean gets placed on the lower byte of the memory on LE, and on the higher byte on BE machines. When using a "Union" to read back the value as a boolean, only the lower byte of the memory location is read which makes it fine on LE machines, however the value will not be present on BE machines. Using an 8 byte data type as boolean will assure the entire filed is read instead of only the lower byte.

This removes the support to emit runtime calls in Liftoff code and uses WebAssembly runtime stubs instead. Calls to such stubs are smaller and more efficient. They also use embedded builtins directly instead of the on-heap {Code} object trampolines. This also removes the last use of a runtime call that passes a dynamically loaded CEntry builtin from the macro assembler.

{WhichPowerOf2} is basically the same as {CountTrailingZeros}, with a restriction to powers of two. Since it does not use or depend on any v8 internals, it can be moved to src/base/bits.h.

In streaming compilation, we were computing a way too low code size estimate, since all {WasmFunction::code} fields were still zero when we were calling {EstimateNativeModuleCodeSize}. This lead to many separate code spaces being created during compilation, creating significant performance and memory overhead. This CL fixes this by passing the code section length when creating the {NativeModule}. From this, we can compute the code size estimate just as before. Drive-by: Rename "functions_count" to "num_functions" in {ProcessCodeSectionHeader} to be consistent with the declaration.

This makes the {code_size_estimate} computation explicit in the caller, and removes one of the two {NewNativeModule} constructors. It turns out that the calculation is totally off in the streaming calculation phase, since no function bodies have been parsed yet. So all {WasmFunction::code} fields are still empty, and we compute an estimate that is way too low. This CL prepares the actual fix for that (by computing a better estimate at specific call sites).
