	* expr.c (get_def_for_expr_class): New function.
	(convert_tree_comp_to_rtx): New function.
	(expand_cond_expr_using_cmove): New function.
	(expand_expr_real_2 <case COND_EXPR>): Call
	expand_cond_expr_using_cmove first and return if it succeeds.
	Remove the check for HAVE_conditional_move since we should have
	already converted it to a conditional move.
	* config/i386/i386.c (ix86_expand_int_movcc): Disallow comparison
	modes of DImode for 32bits and TImode.
