Start a major rewrite of CheckBufferOverrun. For now only the 'array index' and 'buffer overflow' checks are rewritten.
...
There are important TODOs still; for instance adding CTU support using our CTU infrastructure, add handling of pointers (maybe I'll use FwdAnalysis for this), add handling of multidimensional arrays, etc..

checkbufferoverrun: remove dead store

the variable was declared inside a loop and the dead store also took place inside the loop (guarded by a condition) without further access of the value after that store.
Found by clang analyzer.
Was:

tok = tok->next();
