jit_profiling_support
If LLVM has the required functionality, emit the data needed to allow perf to profile functions generated by JIT. This writes out files to ~/.debug/jit/; the user is responsible for performing cleanup when desired. The default setting is off. Only superusers and users with the appropriate SET privilege can change this parameter at session start, and it cannot be changed at all within a session.
