Fix a suspicious check in TargetLibraryInfo

[ab]

Summary

The check for some of the builtin functions involves checking if the number
of the parameter is zero and the first parameter is a pointer type. This check
either returns false or an out-of-bound memory access.

Looks good, but can you test the other changed functions? If you'd like, I can take care of it.

Thanks for adding all the tests! LGTM
