thanks for working on perf profiling support for the jit engines.

Sadly, I still could not find the time to try it out, not even the
simple example from the commit message. 

Also, I'm quite new to llvm and only have some toy examples at the
moment which use orcjit with the SimpleCompiler class. I'm not sure
where to add the perf event listener in all that.

Best regards,
Frank
