[PATCH] Fix SetThreadName with current gdb

[Jon Turney]

Wrap SetThreadName()'s call to RaiseException() in __try/__except/__endtry,
so that if the attached debugger doesn't know about MS_VC_EXCEPTION (e.g.
current gdb and probably strace as well) and continues exception processing,
we ignore it, rather than dying due an unhandled exception.
