aarch64: Add Cygwin and MinGW environments for AArch64
Define Cygwin and MinGW environment such as types, SEH definitions, shared libraries, etc. gcc/ChangeLog: * config.gcc: Add Cygwin and MinGW difinitions. * config/aarch64/aarch64-protos.h (mingw_pe_maybe_record_exported_symbol): Declare functions which are used in Cygwin and MinGW environment. (mingw_pe_section_type_flags): Likewise. (mingw_pe_unique_section): Likewise. (mingw_pe_encode_section_info): Likewise. * config/aarch64/cygming.h: New file.
