Fix multiple_of_p behavior with NOP_EXPR

We were passing down the original type to recursive invocations
of multiple_of_p for say (int)(unsigned * unsigned).

PR tree-optimization/100499
* fold-const.cc (multiple_of_p): Pass the correct type of
the expression to the recursive invocation of multiple_of_p
for conversions and use CASE_CONVERT.
