    [turbofan] Retiring Greedy Allocator · 8e1ccba3
    mtrofin authored
    We were able to achieve our goals for register allocation independent of
    the allocation algorithm. Performance data so far is inconclusive re. the
    value of the Greedy algorithm, compared to the particular Linear Scan
    implementation we're currently using, and the performance measurement
    techniques we currently use are too imprecise to help with this matter.
    
    Retiring the algorithm to lower maintenance and evolution cost (e.g. lower
    cost of adding aliasing support). Once we improve benchmarking stability,
    and establish a suite sensitive enough for codegen improvement studies,
    we may revive the algorithm, should the need arise.
