RFR: 8023720: setjmp/longjmp changes the process signal mask on OS X

[Staffan Larsen]

I have also made a fix for hotspot. I messed up the link in the last email so here are both webrevs.
 
jdk: http://cr.openjdk.java.net/~sla/8023786/webrev.00/
hotspot: http://cr.openjdk.java.net/~sla/8023720/webrev.00/

Thanks,
