[AArch64][SVEIntrinsicOpts] Fix: predicated SVE mul/fmul are not commutative
We can not swap multiplicand and multiplier because the sve intrinsics
are predicated. Imagine lanes in vectors having the following values:
pg = 0
multiplicand = 1 (from dup)
multiplier = 2
The resulting value should be 1, but if we swap multiplicand and multiplier it will become 2,
which is incorrect.
