I'm not certain if my definition of 'aggregate' is correct, but must the fields

Homogeneous Vector Aggregates (with M128 fields). Since the examples given on
the Microsoft pages have array-
like fields, I'm assuming packed (and naturally aligned to 4-byte boundaries
for Singles and 8 bytes for
Doubles).
Well, naturally aligned I think. packed means the whole hfa may be 1 byte
aligned.
The is_hfa() function from aarch64/cpupara.pas could probably be
generalised (so it gets the maximum size/number of elements as
parameter) and be moved to parabase (or to paramgr).
