cmd/compile/internal, runtime: use NOOP for hardware NOPs on loong64
The canonical LoongArch NOP instruction form is "andi r0, r0, 0", as
described in the LoongArch Reference Manual Volume 1, Section 2.2.1.10.
We currently use NOR instead, which may or may not change anything (e.g.
performance on less capable micro-architectures) but is deviation from
upstream standards nevertheless. Fix them to use the explicit hardware
NOP which happens to be supported as `NOOP`.
