Mark Johnston c208cb9923 Allow multiple FBT probes to share a tracepoint. ... With GNU ifuncs, multiple FBT probes may correspond to the same instruction. fbt_invop() assumed that this could not happen and would return after the first probe found in the global FBT hash table, which might not be the one that's enabled. Fix the problem on x86 by linking probes that share a tracepoint and having each linked probe fire when the tracepoint is hit.
