[PATCH v3 14/15] Test on saving tracepoint defs: CTF

[Yao Qi]

Similarly, we have to exercise the CTF code on writing actions to
trace file and restoring them.

gdb/testsuite:

2013-03-08  Yao Qi  <yao@codesourcery.com>

	* gdb.trace/actions.exp: Save trace data to CTF.
	Change to ctf target if GDB supports, read CTF data in ctf
	target, and check the actions of tracepoints.
	* gdb.trace/while-stepping.exp: Likewise.
