Subject: [PATCH] sbc: ensure 16-byte buffer position alignment for 4 subbands encoding

Hello,

Buffer position in X array was not always 16-bytes aligned. Strict 16-byte
alignment is strictly required for powerpc altivec simd optimizations because
altivec does not have support for unaligned vector loads at all.
