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.
