FenceWait: resolve the address into r9, the expected value into rdx, the
poll bound into r8 and the interval into the scratch timespec, then load,
compare, nanosleep, count down. The resolver scratches rax, r10, r11 and
rdi; the system call scratches rax, rcx and r11; r8, r9 and rdx survive
both. A timeout is a command failure; only equality advances.
