* gdb.c++/cplusfuncs.cc (dm_type_char_star): New function.
Helps the test script figure out which demangler is in use.
(dm_type_foo_ref): Ditto.
(dm_type_int_star): Ditto.
(dm_type_long_star): Ditto.
(dm_type_unsigned_int): Ditto.
(dm_type_void): Ditto.
(dm_type_void_star): Ditto.
* gdb.base/cplusfuncs.exp (probe_demangler): New function.
Probe the gdb demangler and set variables to accommodate
formatting differences.
(info_func_regexp): New function.  Same as info_func, but
matches against a regexp.
(info_func): Match against a literal string.
(print_addr_2): New function.  Match against a literal string,
which can be different from the input to gdb.
(print_addr): Simply call print_addr_2 with the same argument twice.
(test_lookup_operator_functions): Use demangler formatting variables.
Blow away the xfails and workarounds for gnats gdb bug gdb/18.  Sort
the tests in the same order as the C++ class declaration.
(test_paddr_operator_functions): Ditto.
(test_paddr_overloaded_functions): Ditto.
(test_paddr_hairy_functions): Use demangler formatting variables.
Add reference to gdb/19 for related tests.
(do_tests): Call probe_demangler.
