8368781: PerfMemory - make issues more transparent

[MBaesken]

Currently issues with perfMemory like problems with the secure tmp subdirectory creation are not very transparent in release JVMs.

There exists some warnings traces but they are behind develop flags like Verbose so only available in debug JVMs.
We could (in case of issues) store some information and write it later into hsinfo/hserr files ; or make the existing warnings available too in release JVMs.
