    * config/i386/i386.c (inline_memory_move_cost):
    Check "in" for 2 in MMX_CLASS_P case.
    * config/i386/mmx.md (*mov<mode>_internal): Correct
    TARGET_INTER_UNIT_MOVES_FROM_VEC and TARGET_INTER_UNIT_MOVES_TO_VEC
    alternatives in preferred_for_speed attribute calculation.

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

Committed to mainline SVN.
