Method GetUnsequencedHashCode

The unordered collection hashcode is defined as the sum of

h(hashcode(item))

over the items

of the collection, where the function

h

is a function from int to int of the form

 t -> (a0*t+b0)^(a1*t+b1)^(a2*t+b2)

, where the ax and bx are the same for all collection classes.

The current implementation uses fixed values for the ax and bx, specified as constants in the code.
