[Bug target/18916] vector code is generated to copy data to mis-aligned memory (-mcpu=G5)

AFAICT, I don't see how gcc middle-end can force correct parameter alignment when alignment is more
strict than PARAM_BOUNDARY. There is no code to do so (I am looking at store_one_arg which is
the one responsible for determining the alignment). It does set the MEM_ALIGN field to 128 in this 
case, but there is no extra padding to move the target address to the next 128 bit boundary.
