7bda28f31f Chaining hash table for repository.Index 
These are faster to construct but slower to access. The allocation rate
is halved, the peak memory usage almost halved compared to standard map.

Benchmark results on linux/amd64, -benchtime=3s -count=20:

68f1e9c524 Update x/crypto to fix poly1305 on ARM 
The broken poly1305 implementation for arm64 was removed, fixing the
segfault issue on arm64 (gh-2618). The version for amd64 has improved
performance, which shows up in the internal/repository benchmark:
