[PATCH] Make GDBJITRegistrar thread-safe

That looks good as an intermediate fix.

In the long term I think the GDB registration should probably be moved out of RuntimeDyldELF (maybe to an event listener), but these changes would probably be nice to have even then.

Subject: [PATCH] Make GDBJITRegistrar thread-safe

Hi there.

While investigating a crash in GDBJITRegistrar I have stumbled upon http://llvm.org/bugs/show_bug.cgi?id=15750 . In my setting there were multiple instances of MCJIT operating in different threads.

Patch from Bugzilla applies cleanly and solves the issue. I have attached a patch against r203780, yet full credit goes to Jim Kearney (jim.kearney at oracle.com<mailto:jim.kearney at oracle.com>), original author of the patch.

Any chances to see this in the trunk or 3.5 release?
