Also, provide the ability to create temporary and non-temporary declarations, as not all declarations may be replaced by definitions later on. This provides the necessary infrastructure for Clang to fix PR19598, leaking temporary MDNodes in Clang's debug info generation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208054 91177308-0d34-0410-b5e6-96231b3b80d8
