To convert the object implicitly, it has had two parts in convert_type() which are
1. lookink up the method's id
2. calling the method
Seems that strncmp() and strcmp() in convert_type() are slightly heavy to look up
the method's id for type conversion.
This patch will add and use internal APIs (rb_convert_type_with_id, rb_check_convert_type_with_id)
to call the method without looking up the method's id when convert the object.

Hash#transform_values! returns the receiver rather than a new Hash
object.

Explicitly says that the methods return a new hash rather than just
stating it return a new something we don't know.

* hash.c (rb_hash_merge): use rb_hash_dup() instead of rb_obj_dup() to duplicate
Hash object. rb_hash_dup() is faster duplicating function for Hash object
which got rid of Hash#initialize_dup method calling.
Hash#merge will be faster around 60%.

* st.c (rb_hash_bulk_insert): new API to bulk insert entries
into a hash. Given arguments are first inserted into the

things using rb_hash_aset() one by one.
This arrangement (rb_ prefixed function placed in st.c) is
unavoidable because it both touches table internal and write
barrier at once.

Same as rb_ary_tmp_new_from_values(), it reduces vm_exec_core binary
size from 26,176 bytes to 26,080 bytes. But this time, also with a
bit of optimizations:
- Because we are allocating a new hash and no back references are
introduced at all, we can safely skip write barriers.
- Also, the iteration never recurs. We can avoid complicated
function callbacks by using st_insert instead of st_update.

extract the bulk insert into a function.
* hash.c (rb_hash_new_from_object): also refactor.

I don't like the idea of making insns.def any bigger to support

how contrived this is.
