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).

In the presence of default arguments, the body of the function gets wrapped into another block. This caused our trailing-range-after-return optimization to not apply, because the wrapper block had no source range assigned. This CL correctly assignes a source range to that block, which allows already present code to handle it correctly. Note that this is not a real coverage bug; we've just been reporting whitespace as uncovered. We're fixing it for consistency.
