Subject: [PATCH 2/2, i386]: Emit inter-unit moves using preferred_for_speed infrastructure

Second part of the patch.

2018-04-27  Uros Bizjak  <ubizjak@gmail.com>

    * config/i386/i386.md (*movti_internal): Substitute Ye constraint
    with Yd constraint. Set "preferred_for_speed" attribute from
    TARGET_INTER_UNIT_MOVES_{FROM,TO}_VEC for alternatives
    with Yd constraint.
    (*movdi_internal): Ditto.
    (movti_interunit splitters): Remove
    TARGET_INTER_UNIT_MOVES_{FROM,TO}_VEC from insn condition.
    (movdi_interunit splitters): Ditto.
    * config/i386/constraints.md (Ye): Remove.
    (Yd): Do not depend on TARGET_INTER_UNIT_MOVES_{FROM,TO}_VEC.

Patch was bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.

Committed to mainline SVN.

Uros.
