Fix clang warnings about copy elision
When building with clang, I get: /home/emaisin/src/binutils-gdb/gdb/osdata.c:107:9: error: moving a temporary object prevents copy elision [-Werror,-Wpessimizing-move] std::move (std::string (body_text))); ^ /home/emaisin/src/binutils-gdb/gdb/osdata.c:107:9: note: remove std::move call here std::move (std::string (body_text))); ^~~~~~~~~~~ ~ /home/emaisin/src/binutils-gdb/gdb/osdata.c:181:10: error: moving a local object in a return statement prevents copy elision [-Werror,-Wpessimizing-move] return std::move (osdata); ^ /home/emaisin/src/binutils-gdb/gdb/osdata.c:181:10: note: remove std::move call here return std::move (osdata); ^~~~~~~~~~~ ~ Indeed, those two std::move are unnecessary. gdb/ChangeLog: * osdata.c (osdata_end_column, get_osdata): Remove std::move.
