Port 9ca0bfef Original Commit Message: This adds feedback collection to count the number of executions of call_direct instructions in Liftoff code. The purpose is better inlining decisions in Turbofan, which are enabled by having call count information for all kinds of calls. The new feature is gated on --wasm-speculative-inlining. While direct calls don't need to speculate about their target, the whole feedback collection infrastructure depends on that flag.
