024b04ad93 First bit of support for the dwarf .loc directive. This patch updates the
needed parsing for the .loc directive and saves the current info from that
into the context.  The next patch will take the current loc info after an
instruction is assembled and save that info into a vector for each section for
use to build the line number tables.  The patch after that will encode the info
from those vectors into the output file as the dwarf line tables.

7859dfd71b MC/Parser: Accept leading dollar signs in identifiers.
- Implemented by manually splicing the tokens. If this turns out to be
   problematically platform specific, a more elegant solution would be to
   implement some context dependent lexing support.

8303a64b0a 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.
