[Yao Qi <yao@codesourcery.com>]

When any location of a tracepoint is downloaded, notify
'breakpoint-modified' observer.

gdb:

2012-12-03  Yao Qi  <yao@codesourcery.com>

	* breakpoint.c (download_tracepoint_locations): Notify
	'breakpoint-modified' observer if any tracepoint location is
	downloaded.
	* tracepoint.c (start_tracing): Likewise.
