Bold just got faster!

Compared to v0.1.0, we notice a 1.19x speed-up when linking Zig stage3 compiler:

Benchmark 1: ./bold.sh
  Time (mean ± σ):     968.2 ms ±   4.5 ms    [User: 3015.3 ms, System: 959.4 ms]
  Range (min … max):   960.0 ms … 972.8 ms    10 runs

Benchmark 2: ./bold-0.1.0.sh
  Time (mean ± σ):      1.148 s ±  0.016 s    [User: 4.639 s, System: 0.903 s]
  Range (min … max):    1.129 s …  1.182 s    10 runs

Summary
  ./bold.sh ran
    1.19 ± 0.02 times faster than ./bold-0.1.0.sh

With this, we have now officially overtaken LLD for this benchmark, but are still behind Apple's rewritten ld64:

Benchmark 1: ./bold.sh
  Time (mean ± σ):     969.4 ms ±   7.5 ms    [User: 3014.2 ms, System: 955.4 ms]
  Range (min … max):   952.4 ms … 978.2 ms    10 runs

Benchmark 2: ./bold-0.1.0.sh
  Time (mean ± σ):      1.150 s ±  0.012 s    [User: 4.680 s, System: 0.894 s]
  Range (min … max):    1.135 s …  1.171 s    10 runs

Benchmark 3: ./ld.sh
  Time (mean ± σ):     445.1 ms ±   7.7 ms    [User: 1773.4 ms, System: 292.3 ms]
  Range (min … max):   438.6 ms … 464.2 ms    10 runs

Benchmark 4: ./lld.sh
  Time (mean ± σ):      1.062 s ±  0.024 s    [User: 1.213 s, System: 0.237 s]
  Range (min … max):    1.043 s …  1.122 s    10 runs

Summary
  ./ld.sh ran
    2.18 ± 0.04 times faster than ./bold.sh
    2.39 ± 0.07 times faster than ./lld.sh
    2.58 ± 0.05 times faster than ./bold-0.1.0.sh
