[PATCH 4/4] Skip breakpoints-invalid annotations for internal|momentary breakpoints.

[Pedro Alves <palves at redhat dot com>]

If a breakpoint is not user visible, then there's no point in
bothering the frontend about it...  This is the exact same check MI
does.

I also smoke tested emacs in gud-gdb mode.  I didn't notice anything break.

2012-11-21  Pedro Alves  <palves@redhat.com>

	* annotate.c (breakpoint_changed): Skip if breakpoint is not
	user-visible.

gdb/testsuite/
2012-11-21  Pedro Alves  <palves@redhat.com>

	* gdb.base/annota1.exp (signal sent): No longer expect
	breakpoints-invalid.
	* gdb.cp/annota2.exp (continue until exit)
	(watch triggered on a.x): Ditto.
