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