[PATCH] aarch64: Implement vmlsl[_high]* intrinsics using builtins

[Kyrylo Tkachov via Gcc-patches]

Hi all,

This patch reimplements some more intrinsics using RTL builtins in the 
straightforward way.
Thankfully most of the RTL infrastructure is already in place for it.

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

Pushing to trunk.
Thanks,
Kyrill
