Description
Since getsolus/packages#4570 and getsolus/packages#4575 BLAKE3 hashes (truncated to 160 bits / 20 bytes) is now supported and is already a fair bit faster than SHA-1.
This issue is for documenting the speedup of XXH3_128bit vs. SHA-1 and BLAKE3 and then making a decision of whether this speedup is sufficient to make it worth pursuing.
See getsolus/packages#1346 for context.

Research direction
Read getsolus/packages#1346 first, along with the changes referenced in getsolus/packages#4570 and #4575. Benchmark XXH3_128bit against SHA-1 and truncated BLAKE3 for build IDs in LLVM, Mold, and Binutils, then document the results and make the go/no-go decision.
