A further step to correctly emitting concrete out of line definitions preceeding inlined instances of the same program. To do this, emission of subprograms must be delayed until required since we don't know which (abstract only (if there's no out of line definition), concrete only (if there are no inlined instances), or both) DIEs are required at the start of the module. To reduce the test churn in the following commit that actually fixes the bug, this commit introduces the lazy DIE construction and cleans up test cases that are impacted by the changes in the resulting DIE ordering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209675 91177308-0d34-0410-b5e6-96231b3b80d8
