[Reassociate] Invalidate analysis passes after canonicalizeOperands (#136835)

When ranking operands for an expression tree the reassociate pass also
perform canonicalization, putting constants on the right hand side. Such
transforms was however not registered as modifying the IR. So at the end
of the pass, if not having made any other changes, the pass returned
that all analyses should be kept.

With this patch we make sure to set MadeChange to true when modifying
the IR via canonicalizeOperands. This is to make sure analyses such as
DemandedBits are properly invalidated when instructions are modified.
