John Ralls bf55c30aeb Fix most of the unused assignment errors from static analysis.
There are a very few left that need deeper study, but this gets
rid of most of the noise. For the most part it's just getting rid of
extra variables or removing an assignment that is always
replaced later but before any reads of the variable. A few are
discarded result variables.
