Log:
    PR tree-optimization/53410
    * fold-const.c (fold_binary_loc): Use build_zero_cst (type)
    instead of build_int_cst (type, 0) where vector types might be
    involved. Instead of build_int_cst (type, 1) convert the original
    integer_onep argument to the desired type.

    * gcc.c-torture/compile/pr53410-1.c: New test.
    * gcc.c-torture/compile/pr53410-2.c: New test.
