PPC has a compare-and-trap instruction that is used for NullChecks and RangeChecks.
If a check fails, SIGTRAP is raised and must be handled by the signal handler of the VM.
Add support for handling SIGTRAP on PPC64 to linux.

----------------------------

This is preparation for PPC64 integration: http://openjdk.java.net/jeps/175
This and following ppc64 changes will go into staging repository first and tested there: http://hg.openjdk.java.net/ppc-aix-port/stage/
