Make PrintCompilation available on a per method level

Especially during development and testing we use -XX:+PrintCompilation to make sure a specific method gets compiled. However, -XX:+PrintCompilation is a global flag which prints all the compilations which can be quite verbose.

It would be therefore desirable to be able to use PrintCompilation on a per method level (e.g. -XX:CompileCommand="option,Inlining::foo,PrintCompilation"). This could be implemented in a way similar to PrintInlining.

As part of this change, the per-method version of PrintInlining should be changed to automatically enable the per-method version of PrintCompilation.
