No, I deleted nds32_type_align completely.  It doesn't have any
special vector type handling, so the default type_align should be
fine.

The one change that will be seen is that the old nds32_type_align
counts static fields within structs when computing the alignment.  I
haven't tried any testing, but I would guess this was a bug.  Unless
someone has the ability to test the target I'll probably just push
this change, and if it turns out the static field handling is wrong,
then it's easy enough to fix later.

Thanks,
Andrew
