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]
