[PATCH, i386]: Use Ym and Yn constraints in Simode interunit moves

[Uros Bizjak]

Hello!

2017-05-16  Uros Bizjak  <ubiz...@gmail.com>

    * config/i386.i386.md (*movsi_internal): Split (?rm,*y) alternative
    to (?r,*Yn) and (?m,*y) alternatives, and (?*y,rm) to (?*Ym,r)
    and (?*y,m).  Update insn attributes.

Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.

Committed to mainline SVN.

Uros.
