* config/i386/i386.h (enum ix86_tune_indices)
<X86_TUNE_INTER_UNIT_MOVES_TO_VEC, X86_TUNE_INTER_UNIT_MOVES_FROM_VEC>:
New, split from X86_TUNE_INTER_UNIT_MOVES.
<X86_TUNE_INTER_UNIT_MOVES>: Remove.
(TARGET_INTER_UNIT_MOVES_TO_VEC): New define.
(TARGET_INTER_UNIT_MOVES_FROM_VEC): Ditto.
(TARGET_INTER_UNIT_MOVES): Remove.
* config/i386/i386.c (initial_ix86_tune_features): Update.
Disable X86_TUNE_INTER_UNIT_MOVES_FROM_VEC for m_ATHLON_K8 only.

TARGET_INTER_UNIT_MOVES_TO_VEC instead of TARGET_INTER_UNIT_MOVES.
(ix86_expand_vector_init_one_nonzero): Ditto.
(ix86_expand_vector_init_interleave): Ditto.
(inline_secondary_memory_needed): Return true for moves from SSE class
registers for !TARGET_INTER_UNIT_MOVES_FROM_VEC targets and for moves
to SSE class registers for !TARGET_INTER_UNIT_MOVES_TO_VEC targets.
* config/i386/constraints.md (Yi, Ym): Depend on
TARGET_INTER_UNIT_MOVES_TO_VEC.
(Yj, Yn): New constraints.
* config/i386/i386.md (*movdi_internal): Change constraints of
operand 1 from Yi to Yj and from Ym to Yn.
(*movsi_internal): Ditto.
(*movdf_internal): Ditto.

(sse2_stored): Change constraint of operand 1 from Yi to Yj.
Use TARGET_INTER_UNIT_MOVES_FROM_VEC instead of
TARGET_INTER_UNIT_MOVES.
(sse_storeq_rex64): Change constraint of operand 1 from Yi to Yj.
(sse_storeq_rex64 splitter): Use TARGET_INTER_UNIT_MOVES_FROM_VEC
instead of TARGET_INTER_UNIT_MOVES.
