i386.c (dimode_scalar_chain::compute_convert_gain): Use xmm_move instead of sse_move.

i386.c (dimode_scalar_chain::compute_convert_gain): Use xmm_move instead of sse_move.

	* i386.c (dimode_scalar_chain::compute_convert_gain): Use
	xmm_move instead of sse_move.
	(sse_store_index): New function.
	(ix86_register_move_cost): Be more sensible about mismatch stall;
	model AVX moves correctly; make difference between sse->integer and
	integer->sse.
	(ix86_builtin_vectorization_cost): Model correctly aligned and unaligned
	moves; make difference between SSE and AVX.
	* i386.h (processor_costs): Remove sse_move; add xmm_move, ymm_move
	and zmm_move. Increase size of sse load and store tables;
	add unaligned load and store tables; add ssemmx_to_integer.
	* x86-tune-costs.h: Update all entries according to real
	move latencies from Agner Fog's manual and chip documentation.
