RFR: 8349523: Unused runtime calls to drem/frem should be removed [v3]

[Marc Chevalier]

> Remove frem and drem macros nodes when the result is not used. These nodes have other outputs (like memory), which is not meaningful, but preventing them to be dropped so easily. This patch removes the useless frem/drem nodes, and by rewiring the inputs to the outputs.
