`cpu_pc` at this point does not necessary point to the current
instruction (i.e., the wait instruction being translated), so it's
incorrect to calculate the new value of `cpu_pc` based on this. It must
be updated with `ctx->base.pc_next`, which contains the correct address
of the next instruction.
This change fixes the wait instruction skipping the subsequent branch
when used in an idle loop like this:
0: wait
bra.b 0b
brk // should be unreachable
