* insns.def: Change the operand type of setinlinecache

(OFFSET to IC).  This IC must be same as corresponding
  getinlinecache instruction's IC operand.
  This change is for a little performance improvement
  (getting IC directly) and is for the AOT compilation development.
* compile.c, iseq.c, insns.def: Change the approach to handling inline
  cahce (IC) type operand to enable the above change.
  This change also affects ISeq#to_a method.  The inline cache operand
  will be dumped by fixnum, the index of inline cache, in other words,
  inline cache identity.
* template/insns_info.inc.tmpl, tool/instruction.rb: No need to count
  inline cache size (insn_iclen()).
