getTTI method used to get an actual TTI object. No functionality changed. This just threads the argument and ensures code like the inliner can correctly look up the callee's TTI rather than using a fixed one. The next change will use this to implement per-function subtarget usage by TTI. The changes after that should eliminate the need for FTTI as that will have become the default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227730 91177308-0d34-0410-b5e6-96231b3b80d8
