The PTRACE_{PEEK,POKE}USR going to get/set tracee's user register.
This patch sets add PTRACE_{PEEK,POKE}USR and compat implement to
riscv.

I notice this issuse when transplanting some app form x86 to riscv
recently.
I don't know why these two function are not implemented now, and I
found few talk about that.

The {PEEK,POKE}USR are both defined in include\uapi\linux\ptrace.h,
So I was thinking maybe these two function shouled be implemented.
