    Pass -Wno-deprecated-register for gdb.cp that use "register"
    
    Clang fails to compile three testcases with the following error:
      warning: 'register' storage class specifier is deprecated and
        incompatible with C++17 [-Wdeprecated-register]
    
    This prevents the following testcases from executing:
      gdb.cp/classes.exp
      gdb.cp/inherit.exp
      gdb.cp/misc.exp
    
    This commit builds those testcases with -Wno-deprecated-register, to
    avoid the failure.  Note that this commit reveals five "wrong access
    specifier for typedef" failures in gdb.cp/classes.exp when compiling
    the testsuite with clang.
    
    gdb/testsuite/ChangeLog:
    
            * gdb.cp/classes.exp (prepare_for_testing): Add
            additional_flags=-Wno-deprecated-register.
            * gdb.cp/inherit.exp (prepare_for_testing): Likewise.
            * gdb.cp/misc.exp: Likewise.
