[PATCH 2/2] opcodes: LoongArch: add "ret" instruction to reduce typing

[WANG Xuerui <i.swmail@xen0n.name>]

From: WANG Xuerui <git@xen0n.name>

This syntactic sugar is present in both classical and emerging
architectures, like Alpha, SPARC and RISC-V, and assembler macros
doing the same thing can already be found in the wild e.g. [1], proving
the feature's popularity. It's better to provide support directly in the
assembler so downstream users wouldn't have to re-invent this over and
over again.
