[llvm-commits] [PATCH] Do not run LoopIdiomRecognizerPass inside memset() and friends.

[arrowdodger]

When compiling
http://llvm.org/svn/llvm-project/klee/trunk/runtime/Intrinsic/memset.c with
-O2, LoopIdiomRecognizer pass inserts memset intrinsic into function body.
It causes recursion during execution in klee. Attached patch fixes this.
