* vm_core.h, compile.c: declare struct iseq_inline_cache_entry.

Browse source 
Inline cache (IC) entries are no longer GC managed object.
  IC entries are freed when ISeq is freed.
* iseq.c: fix mark, free, memsize functions for above change.
* insns.def: remove rb_gc_write_barrier().
* vm_insnhelper.c (vm_method_search): ditto.
* tool/instruction.rb, template/insns_info.inc.tmpl (insn_iclen):
  added.
