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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141227 91177308-0d34-0410-b5e6-96231b3b80d8		2011-10-05 22:27:16 +00:00
