port to linux/loongarch64

[刘小东]

Hi community,

I am from Loongson company (R & D CPU), and we have developed a new RISC CPU instruction architecture named LoongArch with a commercial license.

We have successfully ported linux/loongarch64 in Go version 1.15.6, and want to submit some patches to the Go community to support this port. 

To support linux/loongarch64 port, we have a plan:
(1) provide a builder machine (Loongson 3A5000/2.2GHz,debian-buster / 4.19 linux-kernel) remotely.
(2) submit the patches in August (after Go 1.17 release).
(3) complete the submission and review of all patches by November and be stable state.
(4) maintain linux/loongarch64 port and builder machine for a long time.

Look forward to your reply, thanks!
