    gdb/testsuite: fix gdb.cp/converts.exp to run with clang
    
    Clang attempts to minimize the size of the debug-info by not adding
    complete information about types that aren't constructed in a given
    file.  Specifically, this meant that there was minimal information about
    class B in the test gdb.cp/converts.exp.  To fix this, we just need to
    construct any object of type B in that file.
