8293998: [PPC64] JfrGetCallTrace: assert(_pc != nullptr) failed: must have PC

[TheRealMDoerr]

Backport of JDK-8293998. Linux part applies cleanly modulo file renaming. AIX code was not yet available. I've taken the code from jdk head (part of JFR support JDK-8203290, but also needed for Forte Analyzer AsyncGetCallTrace). It's identical to the linux version except uc_mcontext accesses.
