[codeview] Improve names of types in scopes and member function ids We now include namespace scope info in LF_FUNC_ID records and we emit LF_MFUNC_ID records for member functions as we should. Class names are now fully qualified, which is what MSVC does. Add a little bit of scaffolding to handle ThisAdjustment when it arrives in DISubprogram. llvm-svn: 273358

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
