29-105% faster apply_filter, 6-90% faster ape decoding on core2
(Any x86 other than core2 probably gets much less, since this is mostly due to ssse3 cachesplit avoidance and I haven't written the full gamut of other cachesplit modes.)
9-123% faster ape decoding on G4.

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.

Storing a single element from a vector where all elements have the same
value does not require an aligned destination.  Which element is stored
depends on the alignment of the destination address, but since they all
have the same value, the result is the same regardless of the alignment.

Instead of filling a local array with the desired value and loading it,
load a single element and vec_splat() it to fill the vector.

The Theora decoder depends on the VP3 decoder.

As a side-effect this also gives it the correct value on e.g. PPC970FX-based
PPC64 systems, thus fixing "make test" (mp2/mp3 decoding).

Left to its own devices, gcc calculates the full 64-bit product only to
discard the low 32 bits.  This forces it to do the right thing.

20% faster MP3 decoding on G4.
