Faults that fail the SIR guidelines on fault visibility

The faults listed here should be considered as not representative of real
world faults because the fault is either found too easily (most tests fail
on fault assertion) or are not found (undetected) by the test suite.

Some of these faults are syntactically infeisible and others are simply not
exercised or not evidenced in the test output.
