- vm\_core.h, compile.c: declare struct iseq\_inline\_cache\_entry.  
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.
