Checks if array B is a subset of array A. Array A is assumed to be
pre-sorted in ascending order. Array B doesn't need to be sorted and might
have duplicate elements. It checks if array A contains each item of array B
using binary search. If T is a class or struct, comparison is performed
using T.opCmp(). Otherwise, elements of T are compared using ">" and ">="
or, if T is compatible to size_t (which includes ssize_t, the signed version
of size_t), by calculating the difference.
If both of the arrays are sorted in the same way and don't contain different
number of duplicate items, see mismatch.
