> What does VFENEZBS do? 

VFENE V1, V2, V3 -- vector find element not equal
It elementwise compares V2 and V3. If an unequal element is found, its index is
stored in byte 7th (counting from 0th byte) of V1. If not, the value 16 is
stored in 7th byte (counting from 0th byte) of V1. All other bytes of V1 are
zeroed.

VFENEZBS:
B -- element size is 1 byte
Z -- also compares elements of V2 with zero
S -- set condition code with result of comparation

So,
"VFENEZBS %%v0, %%v0, %%v0" just searchs the first zero byte in %%v0, stores
its  index (or 16 if not found) and indicates if it was found in Conditional
Code (CC).
