bfd macro conversion to inline functions, section

This one exposed a bug in tic6x gas, found with inline function
parameter type checking.  struct bfd_section and struct bfd_symbol
both have a flags field, so bfd_is_com_section (symbol) compiled OK
when bfd_is_com_section was a macro but didn't special case common
symbols.
