Eli Friedman 792860883e PR11061: Make simplifylibcalls fold strcmp("", x) correctly. ...

While I'm here, fix the related issue with strncmp, add some actual tests for strcmp and strncmp, and start using StringRef::compare for constant folding instead of using strcmp/strncmp so that the optimized IR isn't dependent on the host's implementation of strcmp.
