* wide-int.h (multiple_of_p): Define a version that doesn't return
the quotient.
* fold-const.c (extract_muldiv_1): Use wi::multiple_of_p instead of an
integer_zerop/const_binop pair.
(multiple_of_p): Likewise, converting both operands to widest_int
precision.

gcc/testsuite/
* gcc.dg/torture/pr61136.c: New test.
