Add "hppa*-*-hpux*" to setup_xfail for "backtrace through

* gdb.base/signals.exp (test_handle_all_print): Remove code that
increased timeouts, it now makes no difference.
* gdb.base/structs.exp (do_function_calls): Add hppa*-*-hpux9*"
setup_xfails for "p fun5()", "p fun6()", "p fun7()", and "p fun8"
tests.
gdb.c++/virtfunc.exp (do_tests): Add "mips-*-irix5*" setup_xfail
for "runto test_calls(void)" test.

* gdb.base/structs.c: C source for test.
