[ThinLTO] Import only necessary DICompileUnit fields Summary: As discussed on mailing list, for ThinLTO importing we don't need to import all the fields of the DICompileUnit. Don't import enums, macros, retained types lists. Also only import local scoped imported entities. Since we don't currently import any global variables, we also don't need to import the list of global variables (added an assert to verify none are being imported). This is being done by pre-populating the value map entries to map the unneeded metadata to nullptr. For the imported entities, we can simply replace the source module's list with a new list containing only those needed imported entities. This is done in the IRLinker constructor so that value mapping automatically does the desired mapping.

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.

Remove line and file from DINamespace. Fixes the issue highlighted in http://lists.llvm.org/pipermail/cfe-dev/2014-June/037500.html. The DW_AT_decl_file and DW_AT_decl_line attributes on namespaces can prevent LLVM from uniquing types that are in the same namespace.

Debug Info: Add a file: field to DIImportedEntity. DIImportedEntity has a line number, but not a file field. To determine the decl_line/decl_file we combine the line number from the DIImportedEntity with the file from the DIImportedEntity's scope. This does not work correctly when the parent scope is a DINamespace or a DIModule, both of which do not have a source file. This patch adds a file field to DIImportedEntity to unambiguously identify the source location of the using/import declaration. Most testcase updates are mechanical, the interesting one is the removal of the FIXME in test/DebugInfo/Generic/namespace.ll. This fixes PR33822.
