Simon Marchi c93e8391bf Fix internal error when saving fast tracepoint definitions
When trying to save fast tracepoints to file, gdb returns internal failure:

  gdb/breakpoint.c:13446: internal-error: unhandled tracepoint type 27
  A problem internal to GDB has been detected, further debugging may prove unreliable.

And no file including the fast tracepoints definition is created.

The patch also extends save-trace.exp to test saving tracepoint with a
fast tracepoint in there.  Note that because this test doesn't actually
inserts the tracepoints in the program, we can run it with targets that
don't actually support fast tracepoints (or tracepoints at all).

gdb/ChangeLog:

	* breakpoint.c (tracepoint_print_recreate): Fix logic error
	if -> else if.

gdb/testsuite/ChangeLog:

	* gdb.trace/actions.c: Include trace-common.h.
	(main): Add a location for a fast tracepoint.
	* gdb.trace/save-trace.exp: Set a fast tracepoint in addition to
	the normal tracepoints.
	(gdb_verify_tracepoints): Adjust number of expected tracepoints.
