Before we expected all symbols in the device image to be backed up with data that we could read. However, uninitialized values are not. We now check for this case and avoid reading random memory. This also replaces the correct readGlobalFromImage call with a isSymbolInImage check after https://github.com/llvm/llvm-project/pull/74550 picked the wrong one. Fixes: https://github.com/llvm/llvm-project/issues/74582
