This patch series re-implements the store_scatter and load_gather
intrinsincs using the new framework, similarly to previous series.

A few points worth mentioning:

- unlike other intrinsics, these ones have the predicate after the
  mode in their names, hence the need for patch #1

- when checking the 'offset' argument of the *_base_* intrinsics, we
  need ranges with negative lower bounds, unlike what we needed so far
  (SVE does not have such negative bounds AFAIK), hence the need for
  patch #5 and the use of 'ss64' instead of 'su64' in signatures.

- because of some pecularities in ACLE expected output wrt data type
  suffix (.16 vs .u16 vs .f16 for instance), I chose to update a few
  tests in patches #12 and #13, and to introduce a dedicated iterator
  in other cases (patch#10, using and fixing an existing iterator
  would have impact on Neon tests).  I chose the approach which seemed
  the less invasive, but maybe we should aim at more consistency and
  update ACLE instead?

Thanks,

Christophe
