watson1978 d0015e4ac6 Improve performance of implicit type conversion
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.

watson1978 6e0e067de3 Improve performance of rb_equal()
* object.c (rb_equal): add optimized path to compare the objects using
    rb_equal_opt(). Previously, if not same objects were given, rb_equal() would
    call `==' method via rb_funcall() which took a long time.

    rb_equal_opt() has provided faster comparing for Fixnum/Float/String objects.
    Now, Time#eql? uses rb_equal() to compare with argument object and it will
    be faster around 40% on 64-bit environment.

* array.c (rb_ary_index): remove redundant rb_equal_opt() calling.
    Now, rb_equal() was optimized using rb_equal_opt().
    If rb_equal_opt() returns Qundef, it will invoke rb_equal() -> rb_equal_opt(),
    and it will cause the performance regression.

    So, this patch will remove first redundant rb_equal_opt() calling.

* array.c (rb_ary_includes): ditto.

watson1978 044257c046 Improve performance in where push the element into non shared Array object
* array.c (ary_ensure_room_for_push): use rb_ary_modify_check() instead of
    rb_ary_modify() to check whether the object can be modified for non shared
    Array object. rb_ary_modify() has the codes for shared Array object too.
    In here, it has condition branch for shared / non shared Array object and
    it can use rb_ary_modify_check() which is smaller function than
    rb_ary_modify() for non shared object.

    rb_ary_modify_check() will be expand as inline function.
    If it will compile with GCC, Array#<< will be faster around 8%.

normal eeb36c5c74 mention behavior of Array#join for nested arrays [ci skip]
The current documentation for Array#join does not mention the
special treatment of nested arrays.

It says:
> Returns a string created by converting each element of the
> array to a string, separated by the given separator.

Expected behavior according to the docs would be:

    [ "a", [1, 2, [:x, :y]], "b" ].join("-")  #=> "a-[1, 2, [:x, :y]]-b"
    # because of:
    [1, 2, [:x, :y]].to_s  #=> "[1, 2, [:x, :y]]"

Actual behavior:

    [ "a", [1, 2, [:x, :y]], "b" ].join("-")  #=> "a-1-2-x-y-b"

because join is applied recursively for nested arrays.

The patch clarifies this behavior.

(Also: small markup and grammar fix.)

rhe b5da45d6d7 array.c: do not resize to less than 0
Shrinking the Array from the block invoked by Array#select! or
Array#reject! causes the Array to be a negative number size. Ensure that
the resulting Array won't be smaller than 0.

rhe 647ba111ea array.c: check array length every time after yielding
Since the Array may be modified during rb_yield(), the length before
invoking the block can't be trusted. Fix possible out-of-bounds read in
Array#combination and Array#repeated_combination.

It may better to make a defensive copy of the Array, but for now let's
follow what Array#permutation does.  [ruby-core:78738] [Bug #13052]

a_matsuda f12003d372 Update documentation of fetch
The sentence `Negative values of +index+ count from the end of the array.` can be interpreted that it only holds if a block is given. Clarify it.
