add killing of non-volatile loads
OP_LOADs were ignored by kill_instruction() but there are two cases
were something can or must be done:
1) if the is not a volatile one, it is free of side-effects and can thus
be optimized away like others instructions.
2) if force-killed then we need to adjust the usage of its operand.
