[PATCH 2/5] Add CodeView enum cv_sym_type

[Mark Harmstone]

Make everything more gdb-friendly by using an enum for symbol constants
rather than #defines.

    gcc/
            * dwarf2codeview.cc (S_LDATA32, S_GDATA32, S_COMPILE3): Undefine.
            (enum cv_sym_type): Define.
            (struct codeview_symbol): Use enum cv_sym_type.
            (write_codeview_symbols): Add default to switch.
