[PATCH] aarch64: Make sqdmlal2 patterns match canonical RT

[Kyrylo Tkachov via Gcc-patches]

Hi all,

The sqdmlal2 patterns are hidden beneath the SBINQOPS iterator and 
unfortunately they don't match
canonical RTL because the simple accumulate operand comes in the first arm of 
the SS_PLUS.
This patch splits the SS_PLUS and SS_MINUS forms with the SS_PLUS operands set 
up to match
the canonical form, where the complex operand comes first.

Bootstrapped and tested on aarch64-none-linux-gnu.
Pushing to trunk.
Thanks,
Kyrill
