[PATCH 1/5] Cleanup tsv.exp

[Yao Qi <yao at codesourcery dot com>]

This patch remove some code in tsv.exp which is not related to testing
TSV, for example, there are three tracepoints created in it but only
one is used.  Don't have to create the rest of two tracepoints at all.

gdb/testsuite:

2013-03-07  Yao Qi  <yao@codesourcery.com>

	* gdb.trace/tsv.exp: Remove code unrelated to testing TSV.
	Replace some "gdb_test" with "gdb_test_no_output".
