  1. Optimize string comparison by using memcmp 

    llvm seems to be having some trouble optimizing the iterator-based
string comparsion method into some equivalent to memcmp. This
explicitly calls out to the memcmp intrinisic in order to allow
llvm to generate better code. In some manual benchmarking, this
memcmp-based approach is 20 times faster than the iterator approach.
