Jakob Kummerow 5d75bd1fdb [wasm-gc] Speculative inlining for call_ref (off by default)
This patch adds infrastructure for collecting feedback about call_ref
call targets in Liftoff code, and using that feedback for turning
such calls into inlineable direct calls when building Turbofan graphs.
The feature is considered experimental quality and hence off by default,
--wasm-speculative-inlining turns it on.
