LLVM backend: generate DIGlobalVariable's for non-function globals and rename linkage names when exporting functions and globals. zig_llvm.cpp: add some wrappers to convert a handful of DI classes into DINode's since DIGlobalVariable is not a DIScope like the others. zig_llvm.cpp: add some wrappers to allow replacing the LinkageName of DISubprogram and DIGlobalVariable. zig_llvm.cpp: fix DI class mixup causing nonsense reinterpret_cast. The end result is that GDB is now usable since you now no longer need to manually cast every global nor fully qualify every export.
