The stack is aligned at 16 bytes with AltiVec (if not, this patch would
not make sense).
Also, all char arrays are aligned at 16 bytes.
This patch causes other local stack arrays >= 16 bytes to be aligned at
16 bytes in order to
make more effective use of AltiVec instructions.

Wait I thought the alignment of the stack is 16 bytes so this patch is
normally not needed except for the case where someone does not use
-mabi=altivect.
