    Tune heuristics for feedback vector allocation · 9ca74651
    Mythri A authored
    Recently we changed feedback vector allocation to be based on the
    bytecode size of the function. The threshold at which the feedback
    vectors are allocated was set to 12 * bytecode size of the function.
    This caused a couple of regressions on IC:duration and some regressions
    on other benchmarks. To avoid these regressions this cl reduces the
    scale factor to 8 instead of 12.
