    [wasm][gc] Fix several minor issues · 0820ee1a
    Clemens Hammacher authored
    This CL fixes some issues with GC.
    1) It removes dead code from the set of potentially dead code to avoid
       considering the same code for GC again and again.
    2) It resets the {new_potentially_dead_code_size_} counter to avoid
       triggering too many GCs.
    3) When code becomes dead after GC, do not unconditionally free it; just
       decrement its ref count (there might still be {WasmCodeRefScope}s
       holding the code alive).
    4) Update the comment of the ref count to be more accurate.
