Debug Info Verifier: enable verification of DICompileUnit. We used to call Verify before adding DICompileUnit to the list, and now we remove the check and always add DICompileUnit to the list in DebugInfoFinder, so we can verify them later on. llvm-svn: 187237

Remove the (apparently) unnecessary debug info metadata indirection. The main lists of debug info metadata attached to the compile_unit had an extra layer of metadata nodes they went through for no apparent reason. This patch removes that (& still passes just as much of the GDB 7.5 test suite). If anyone can show evidence as to why these extra metadata nodes are there I'm open to reverting this patch & documenting why they're there. llvm-svn: 174266

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. llvm-svn: 189282

Split out filename & directory from DIFile to start generalizing over DIScopes This is the first step to making all DIScopes have a common metadata prefix (so that things (using directives, for example) that can appear in any scope can be added to that common prefix). DIFile is itself a DIScope so the common prefix of all DIScopes cannot be a DIFile - instead it's the raw filename/directory name pair. llvm-svn: 177239
