Subject: 	* compile.c (iseq_compile_each): share InlineCache during same
 	  instance variable accesses. Reducing memory consumption, 	 
 rasing cache hit rate and rasing branch prediction hit rate 	  are
 expected. A part of [Bug #12274].

	* iseq.h (struct iseq_compile_data): introduce instance
	  variable IC table for sharing.

	* iseq.c (prepare_iseq_build, compile_data_free):
	  construct/destruct above table.
