cace411974 C++: NonConstantFormat taint only for string types 
To speed up the taint analysis in `NonConstantFormat.ql` and to remove
FPs that were due to taint spreading from `i` to `a[i]`, this commit
stops the taint tracking in `NonConstantFormat.ql` at every node that
could not possibly contain a string.

I tested performance on Wireshark, and it's fine. Pulling out the
`isSanitizerNode` prevented `isSanitizer` from turning into four
half-slow RA predicates due to both CPE and `#antijoin_rhs`
transformations happening.
