    Bolt instrumentation is failing when trying to instrument mysqld when target is RISCV

-  Bolt is the extreme version of 19.x, and I have implemented the instrumentation for target RISCV.
- it works fine when i build mysqld with gcc，but it fails when i use llvm
- llvm-bolt --instrumentation-file-append-pid --instrumentation-file=/home/compiler-test/perf/mysqld --instrument ./mysqld -o mysqld.inst
