* pe-dll.c (pe_details_type): Add new pointer for symbols list autofilter.

Browse source 
(autofilter_symbollist): Split into autofilter_symbollist_generic and
    autofilter_symbollist_i386.
  (pe_detail_list): Add autofilter_symbollist_i386 to i386 case and
    autofilter_symbollist_generic for all the others.
  (autofilter_symbolprefixlist): Moved _fmode, _impure_ptr, cygwin_attach_dll,
    cygwin_premain0, cygwin_premain1, cygwin_premain2, cygwin_premain3,
    environ, into autofilter_symbollist_i386.
  (auto_export): Get autofilter_symbollist from pe_details.
