[PATCH] Filter tracepoints out of bpstat


It can happen that if a breakpoint and tracepoint are at the same address and the breakpoint is hit, GDB gets confused and ultimately internal-errors in bpstat_what. This patch simply dismisses apparent tracepoint hits as not being possible, which lets GDB go on to interpret the stop correctly.

Committed to trunk.
