tree.c (tree_fold_gcd): Delete.
* tree.c (tree_fold_gcd): Delete.
* tree.h (tree_fold_gcd): Remove prototype.
* tree-data-ref.c (tree_fold_divides_p): Don't use tree_fold_gcd to
test whether one constant integer is a multiple of another. Instead
call int_const_binop with TRUNC_MOD_EXPR and test for a zero result.
* fold-const.c (multiple_of_p): We've determined both TOP and
BOTTOM are integer constants so we can call int_const_binop directly
instead of the more generic const_binop.
