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.

the info from the .file directive and makes file and directory tables that
will eventually be put out as part of the dwarf info in the output file.

fix a memory leak yjasskin pointed out: MCSymbol is bump pointer

allocated and thus not freed. This is cool except that it contains

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.
