PR middle-end/32628
* c-common.c (pointer_int_sum): Disregard overflow that occured only
because of sign-extension change when converting to sizetype here...
* fold-const.c (fold_convert_const_int_from_int): ...and not here.

* fold-const.c (fold_binary_op_with_conditional_arg): Do not restrict
the folding to constants.  Remove redundant final conversion.
(fold_binary) <associate>: Do not associate if the re-association of
constants alone overflows.
(fold_binary) <FLOOR_MOD_EXPR>: Move transformation into BIT_AND_EXPR
to the end of the list.
(multiple_of_p) <COND_EXPR>: New case.
