Fix ThinLTO crash with debug info Because the recent change about ODR type uniquing in the context, we can reach types defined in another module during IR linking. This triggered some assertions in case we IR link without starting from an empty module. To alleviate that, we can self-map metadata defined in the destination module so that they won't be visited.

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.

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144

Verifier: Disallow a line number without a file in DISubprogram A line number doesn't make much sense if you don't say where it's from. Add a verifier check for this and update some tests that had bogus debug info. llvm-svn: 295516
