Alexander Potapenko 5478afc55a kmsan: fix memcpy tests ... Recent Clang changes may cause it to delete calls of memcpy(), if the source is an uninitialized volatile local. This happens because passing a pointer to a volatile local into memcpy() discards the volatile qualifier, giving the compiler a free hand to optimize the memcpy() call away. Use OPTIMIZER_HIDE_VAR() to hide the uninitialized var from the too-smart compiler.
