[PATCH] aarch64: Reimplement vabdl_high* intrinsics using builtins

[Kyrylo Tkachov via Gcc-patches]

Hi all,

This patch reimplements the vabdl_high intrinsics using builtins.
It slightly cleans up the RTL pattern (the mode iterators) but nothing 
interesting apart from that.

Bootstrapped and tested on aarch64-none-linux-gnu and aarch64_be-none-elf.

Pushing to trunk.
Thanks,
Kyrill
