Properly mark IR changed if instruction folder creates more than one constant. (#3799)

In #3636, I missed that the instruction folder may create more than a
single constant per call.  Since CCP was only checking whether one
constant had been created after folding, it was wrongly thinking that
the IR had not changed.

Fixes #3738.
