Update StripDeadDebugInfo to use DebugInfoFinder so that it is no longer stale to the point of not working and more resilient to debug info changes. The current version of StripDeadDebugInfo became stale and no longer actually worked since it was expecting an older version of debug info. This patch updates it to use DebugInfoFinder and the modern DebugInfo classes as much as possible to make it more redundent to such changes. Additionally, the only place where that was avoided (the code where we replace the old sets with the new), I call verify on the DIContextUnit implying that if the format changes and my live set changes no longer make sense an assert will be hit. In order to ensure that that occurs I have included a test case. The actual stripping of the dead debug info follows the same strategy as was used before in this class: find the live set and replace the old set in the given compile unit (which may contain dead global variables/functions) with the new live one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189078 91177308-0d34-0410-b5e6-96231b3b80d8

Debug Info: add an identifier field to DICompositeType. DICompositeType will have an identifier field at position 14. For now, the field is set to null in DIBuilder. For DICompositeTypes where the template argument field (the 13th field) was optional, modify DIBuilder to make sure the template argument field is set. Now DICompositeType has 15 fields. Update DIBuilder to use NULL instead of "i32 0" for null value of a MDNode. Update verifier to check that DICompositeType has 15 fields and the last field is null or a MDString. Update testing cases to include an extra field for DICompositeType. The identifier field will be used by type uniquing so a front end can genearte a DICompositeType with a unique identifer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189282 91177308-0d34-0410-b5e6-96231b3b80d8
