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.
