cmd/asm: add RDTIME{L,H}.W, RDTIME.D support for loong64

Instruction formats: rdtime rd, rj

The RDTIME family of instructions are used to read constant frequency timer
information, the stable counter value is written into the general register
rd, and the counter id information is written into the general register rj.
(Note: both of its register operands are outputs).
