Add Nix recipe for collecting linker reproducers. (#145789)
As proposed in:
https://discourse.llvm.org/t/improving-the-reproducibility-of-linker-benchmarking/86057
This is a Nix recipe for collecting reproducers for benchmarking
purposes
in a reproducible way. It works by injecting a linker wrapper that
embeds
a reproducer tarball into a non-allocated section of every linked
object,
which generally causes them to be smuggled out of the build tree in a
section of the final binaries.
It may be used in conjunction with the script lld/utils/run_benchmark.py
to measure the relative performance of linker changes or compare
the performance of different linkers.
