array.c: speedup Array#unshift by using space in shared array
* array.c: speedup Array#unshift by using space in shared array.
[Feature #6638]
- when array owns its shared array (ARY_SHARED_NUM == 1), and there
is enough space then try unshift values directly into shared
array.
- when resulting array is big (~>64 items) then make it shared with
enough room for future #unshifts, and then insert into shared
array.
