vec_cmpeq_or_0_idx_cc: Vector Compare Equal or Zero Index with Condition Code

d = vec_cmpeq_or_0_idx_cc(a, b, c)

Returns the lowest byte-index of comparing each set of corresponding elements of the given vectors for equality, and comparing each elements of a against 0. If the two vectors are not equal, and no elements of a is 0, the result is 16.

c would be set to one of the following values:

0 - if no elements of the 2 vectors are equal, and at least one element from a with a value of 0.
1 - if at least one element of a equals the corresponding element of b, and no elements of a has a value of 0.
2 - if at least one element of a equals the corresponding element of b with an equal value, and there is at least one element from a has a value of 0.
3 - if no element of a equals the corresponding element of b, and there is no element from a with a value of 0.

The result is placed into byte element seven of the returned vector, and all other bytes are set to 0.
