XieJiSS 8b1df101da fix: build on risc-v (#9215)
Summary:
Patch is modified from ~~https://reviews.llvm.org/file/data/du5ol5zctyqw53ma7dwz/PHID-FILE-knherxziu4tl4erti5ab/file~~

Tested on Arch Linux riscv64gc (qemu)

UPDATE: Seems like the above link is broken, so I tried to search for a link pointing to the original merge request. It turned out to me that the LLVM guys are cherry-picking from `google/benchmark`, and the upstream should be this:

808571a52f/src/cycleclock.h (L190)

The files in this directory originally come from
https://github.com/percona/PerconaFT/.

This directory only includes the "locktree" part of PerconaFT, and its
dependencies.

The following modifications were made:
- Make locktree usable outside of PerconaFT library
- Add shared read-only lock support

The files named *_subst.* are substitutes of the PerconaFT's files, they
contain replacements of PerconaFT's functionality.
