commit af7ce09b7685050d2ca1a8a746bb8a8c080fff69

    gdb: move struct reggroup into reggroups.h header
    
    Move 'struct reggroup' into the reggroups.h header.  Remove the
    reggroup_name and reggroup_type accessor functions, and just use the
    name/type member functions within 'struct reggroup', update all uses
    of these removed functions.
    
    There should be no user visible changes after this commit.
