Store Vector Indexed

`vec_st(arg1, arg2, arg3) vec_stl(arg1, arg2, arg3)`

The 16-byte value of arg1 is stored to a 16-byte aligned address. arg2 is an integer value, while arg3 is a pointer. arg2 is added to arg3 and the sum is truncated, if necessary, to produce a 16-byte aligned result. The arg3 type may also be a pointer to a const-qualified type. The result of the operation is void.
vec_stl marks the data as Least Recently Used (LRU), while vec_st does not; otherwise the instructions are identical.

See AltiVec Alignment for a discussion of how to store data that may not be 16-byte aligned.
