395b962c3d [Mach-O] Use SHA1 instead of SHA256 for code signature 
It looks like SHA1 is slightly faster than SHA256 on a 2021 ARM Mac mini.
SHA1 is not recommended anymore, but for ad-hoc code signing, it should
be enough because anyone can just recompute an ad-hoc code signature for
any arbitrary binary.

45615c9d81 [Mach-O] Speed up code signature computation 
It looks like calling msync with MS_ASYNC can save ~130 ms per 1 GiB
output on an ARM Mac Mini 2021.

79654bfde0 [Mach-O] Parallelize file parsing 
`make test-tsan` started failing with this change, but I believe it
is an internal failure of Intel TBB itself.

f55fd7d9f2 [Mach-O] Compute LC_UUID as a tree hash of ad-hoc code signatures 
We need to compute SHA256 hashes for a __code_signature section,
so recomputing a SHA256 hash of an entire file for an LC_UUID is
a waste of time. We can instead compute it as a tree hash.

16735e1e68 [ELF] Simplify range extension thunk algorithm 
We eliminate unneeded symbols at the end of the algorithm, but that
didn't save too much space. In fact, I didn't observe any difference
by eliminating that last step from the algorithm.
