Give the target more control over ARRAY_TYPE modes
So far we've used integer modes for LD[234] and ST[234] arrays.
That doesn't scale well to SVE, since the sizes aren't fixed at
compile time (and even if they were, we wouldn't want integers
to be so wide).
This patch lets the target use double-, triple- and quadruple-length
vectors instead.
