Fix SetThreadName with current gdb

Browse Source 
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.

Also remove an unnecessary cast in the RaiseException() invocation.
