available_externall linkage is not local, this was confusing the codegenerator,
and it wasn't generating calls through @PLT for these functions. hasLocalLinkage() is now false for available_externally, I attempted to fix the inliner and dce to handle available_externally properly. It passed make check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72328 91177308-0d34-0410-b5e6-96231b3b80d8
