Next bit of support for the dwarf .file directive. This patch takes the
previously collected info from the .file directives and outputs the encoded
bytes for it. For now this is only in the Mach-O streamer but at some point
will move to a more generic place.

fix a memory leak yjasskin pointed out: MCSymbol is bump pointer
allocated and thus not freed. This is cool except that it contains
and std::string so the string data didn't get freed. In any case
there is no reason to redundantly store the string data in the
MCSymbol anyway, just make the MCSymbol ref the string data in the
MCContext StringMap.
