feat(invoker): add compiler hints chore(get network event data): added translation TODO feat(native hooks): add compiler hint to crashes feat(render): add likely compiler hint to on_present feat(thread pool): add compiler hints Added hook likely/unlikely switches to debug/crash scenarios. Added HEX_TO_UPPER call on the AC verifier offsets. Added more fuzzer unlikely attributes. Replaced some hard coded numbers with their unhashed _J variants. Added more unlikely attributes to singleton initializer checks. Added more likely/unlikely attributes to certain scenarios.
