With -msve-vector-bits=N, the payload of some partial SVE modes can
be 16 bytes or smaller, which makes them small enough to fit in a
pair of GPRs.  We specifically don't want that, because the payload
is distributed evenly across the SVE register rather than collected
at one end.  Marshalling it into a GPR via register operations would
be expensive.

From-SVN: r279174

The INDEX patterns handle partial modes by choosing the container
size rather than the element size, so that the number of lanes
(and thus number of additions) matches the mode.  This means that
all VNx4 modes use .s and all VNx2 modes use .d, etc.

When adding this, I'd forgotten that the choice between Wn and Xn
registers would need to be updated to use the container size too.
For partial VNx2s, we were using .d containers with Wn rather than
Xn source registers.

The dwarf2 handling of vector constants currently divides the vector
into a length (number of elements) and byte element size.  This doesn't
work well for MODE_VECTOR_BOOL, where several elements are packed into

We should probably add a way of encoding this in future, but for now
the safest thing is to punt, like we already do for variable-length
vectors.

Unlike most vector ops, extract-last reductions replace the original
scalar code in-situ rather than adding an adjacent vector implementation.
I.e.:
