    [wasm] Basic wasm tier-up · e47072c9
    Kim-Anh Tran authored
    Wasm tier-up first compiles the whole module using Liftoff, and then
    using Turbofan. The idea is to achieve fast start-up times by first
    running Liftoff-compiled code. In the meantime we finish compilation
    with Turbofan, and replace the Liftoff-compiled code as soon
    as Turbofan finished compilation, thus achieving high performance.
    Tier-up is enabled through the flag FLAG_wasm_tier_up.
