f231ce5ce3 Remove old false positive avoidance code 
From email explaining existence in the first place:

    This is from before when the used checks throwing false
    positives about unused due to changing the definition without
    checking whether it *had* a value to begin with and me not
    realizing they were false positives. I was thinking that it was
    warning from ARGC et. al. not being used since the previous
    macro or function call and the new value warning about
    overwriting the old value.

a117e02cc8 Revert "Add test for unused warnings at the end of scope" 
This reverts commit 91c4c9921c40361df860c1384a46ed77c6118c23.

The test doesn't work yet and should not have been put on this branch
yet.
