Add debug trace in amd64-windows-tdep.c::amd64_windows_frame_decode_insns
This is a trace which would have been useful when trying to understand why the debugger was not decoding the stream of unwind codes I was expecting. This patch adds a trace first informing us that we are following the unwind info to the next unwind record in that chain. gdb/ChangeLog: * amd64-windows-tdep.c (amd64_windows_frame_decode_insns): Add debug trace.
