change `cfunc->invoker` type for opt. 

* vm_insnhelper.c: change `call_cfunc_*` parameters order
  and specify a function type for the passed func ptr.
  This fix reduce the number of asm instructions, such as:
    # before this patch
    0000000000000110 <call_cfunc_0>:
     110:       48 89 fa                mov    %rdi,%rdx
     113:       31 c0                   xor    %eax,%eax
     115:       48 89 f7                mov    %rsi,%rdi
     118:       ff e2                   jmpq   *%rdx
     11a:       66 0f 1f 44 00 00       nopw   0x0(%rax,%rax,1)

    # after this patch
    0000000000000110 <call_cfunc_0>:
     110:       ff e1                   jmpq   *%rcx

  However, this kind of instruction reduction doesn't affect
  any performance because of great CPU architectures :p
