[RFA] Typedef support for linespecs

[Keith Seitz <keiths at redhat dot com>]

Hi,

CVS HEAD currently fails if a user does something like:

class foo
{
public:
  void a_function (void) { }
};
typedef MyFoo foo;
MyFoo instance;

(gdb) list MyFoo::a_function

This happens because when we lookup "MyFoo", lookup_prefix_sym will only 
search STRUCT_DOMAIN, and it won't find "MyFoo", since typedefs live in 
VAR_DOMAIN.

The attached patch attempts to address this issue by searching 
VAR_DOMAIN if the search through STRUCT_DOMAIN fails.

[In case I am not always explicit: This patch introduces no regressions 
or failures/errors of any kind with the test suite on x86 linux.]
