Zifencei emulaton was added for bare bones 32-bit targets, but the code
is there on 64-bit too. The instruction skip at the end of the function
skips 4 bytes, the size of an instruction on both rv32 and rv64. The
instruction decoder however assumes instructions are size(long) bytes,
which is 8 > 4 on rv64. Fix this.
