* fold-const.c (fold_comparison): New subroutine of fold_binary
	containing transformations common to both the equality and
	ordering relational operators, factored out of fold_binary.
	(fold_binary): Separate out the equality operators (EQ_EXPR
	and NE_EXPR) from the ordering operators (LT_EXPR, GT_EXPR,
	LE_EXPR and GE_EXPR), calling fold_comparison to perform the
	transformations common to both.
	(fold_div_compare): Fix latent bugs in the previously unreachable 
	LT_EXPR and GE_EXPR cases.
