LoongArch: Add checksum optimization for 64-bit system
LoongArch platform is 64-bit system, which supports 8-bytes memory
accessing, but generic checksum functions use 4-byte memory access.
So add 8-bytes memory access optimization for checksum functions on
LoongArch. And the code comes from arm64 system.
When network hw checksum is disabled, iperf performance improves about
10% with this patch.
