What happened to llvm::PerformTailCallOpt?

I'm just trying to test HLVM with the latest SVN of LLVM and discovered that
llvm::PerformTailCallOpt has disappeared from the code but it is still
referred to from LangRef.html.

Where did it go?

It got renamed to GuaranteedTailCallOpt, to better reflect what it actually represents.

Ah, great. Thanks!
