[PATCH][committed] aarch64: Convert SVE gather patterns to compact syntax

[Kyrylo Tkachov via Gcc-patches]

Hi all,

This patch converts the SVE load gather patterns to the new compact syntax
that Tamar introduced. This allows for a future patch I want to contribute
to add more alternatives that are better viewed in the more compact form.

The lines in some patterns are >80 long now, but I think that's unavoidable
and those patterns already had overly long constraint strings.

No functional change intended.
Bootstrapped and tested on aarch64-none-linux-gnu.
Pushing to trunk.
Thanks,
Kyrill
