Akira Hatanaka 187770dc74 [CodeGen][ObjC] Remove the leading l_ from ObjC symbols and make
private symbols in the __DATA segment internal.

This prevents the linker from removing the symbol names. Keeping the
symbols visible enables tools to collect various information about the
symbols, for example, tools that discover whether or not a symbol gets
dirtied.
