Fuzzer for the remaining INT PIPs

Run this fuzzer a few times until it produces an empty todo.txt file (make run will run this loop).

This fuzzer occationally fails (depending on some random variables). Just restart it if you encounter this issue. The script behind make run automatically handles errors by re-starting a run if an error occurs.

Solvability

Known issues:

• INT.CTRL0: goes into CLB's SR. This cannot be routed through

Jenkins build 3 (78fa4bd5, success) for example solved the following types:

• INT_L.EE4BEG0.LH12
• INT_L.FAN_ALT1.GFAN1
• INT_L.FAN_ALT4.BYP_BOUNCE_N3_3
• INT_L.LH0.EE4END3
• INT_L.LH0.LV_L9
• INT_L.LH0.SS6END3
• INT_L.LVB_L12.WW4END3
• INT_L.SW6BEG0.LV_L0
