* Add two strlen optimizations:
...
strlen(x) != 0 -> *x != 0
strlen(x) == 0 -> *x == 0
* Change nested statistics to use style of other LLVM statistics so that
only the name of the optimization (simplify-libcalls) is used as the
statistic name, and the description indicates which specific all is
optimized. Cuts down on some redundancy and saves a few bytes of space.
* Make note of stpcpy optimization that could be done.
