Temporarily revert "Don't try to construct debug LexicalScopes hierarchy for functions that do not have top level debug information." as it appears to be breaking some LTO constructs.
This reverts commit r212203. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212298 91177308-0d34-0410-b5e6-96231b3b80d8
