Vectorise conversions between differently-sized integer vectors
This patch adds AArch64 patterns for converting between 64-bit and
128-bit integer vectors, and makes the vectoriser and expand pass
use them.

* tree-cfg.c (verify_gimple_assign_unary): Handle conversions
between vector types.
* tree-vect-stmts.c (vectorizable_conversion): Extend the
non-widening and non-narrowing path to handle standard
conversion codes, if the target supports them.
* expr.c (convert_move): Try using the extend and truncate optabs
for vectors.
* optabs-tree.c (supportable_convert_operation): Likewise.
* config/aarch64/iterators.md (Vnarroqw): New iterator.
* config/aarch64/aarch64-simd.md (<optab><Vnarrowq><mode>2)
(trunc<mode><Vnarrowq>2): New patterns.
