Minor testsuite fixes

[law at redhat dot com]

The first two changes remove bogus xfails for the PA.  The 3rd change updates
annota2.exp to handle systems with hardware watchpoints.

Cheers,

	* gdb.base/selftest.exp (backtrace through signal handler): Remove
	hppa*-*-hpux* expected failure.
	* gdb.base/structs.exp (do_function_calls): Similarly.

	* gdb.c++/annota2.exp (watch triggered on a.x): Handle hardware
	watchpoints.
