ppc: fix Altivec build with old compilers
...
The vec_splat() intrinsic requires a constant argument for the
element number, and the code relies on the compiler unrolling
the loop to provide this. Manually unrolling the loop avoids
this reliance and works with all compilers.

Drop unused args from vector_fmul_add_add, simpify code, and rename

The src3 and step arguments to vector_fmul_add_add() are always zero
and one, respectively. This removes these arguments from the function,
simplifies the code accordingly, and renames the function to better
match the new operation.
