-    CXX_FAST_TLS calling convention: performance improvement for PPC64
-    
-    This is the same change on PPC64 as r255821 on AArch64. I have even borrowed
-    his commit message.
-    
-    The access function has a short entry and a short exit, the initialization
-    block is only run the first time. To improve the performance, we want to
-    have a short frame at the entry and exit.
-    
-    We explicitly handle most of the CSRs via copies. Only the CSRs that are not
-    handled via copies will be in CSR_SaveList.
-    
-    Frame lowering and prologue/epilogue insertion will generate a short frame
-    in the entry and exit according to CSR_SaveList. The majority of the CSRs will
-    be handled by register allcoator. Register allocator will try to spill and
-    reload them in the initialization block.
-    
-    We add CSRsViaCopy, it will be explicitly handled during lowering.
-    
-    1> we first set FunctionLoweringInfo->SplitCSR if conditions are met (the target
-       supports it for the given machine function and the function has only return
-       exits). We also call TLI->initializeSplitCSR to perform initialization.
-    2> we call TLI->insertCopiesSplitCSR to insert copies from CSRsViaCopy to
-       virtual registers at beginning of the entry block and copies from virtual
-       registers to CSRsViaCopy at beginning of the exit blocks.
-    3> we also need to make sure the explicit copies will not be eliminated.
