In the default address space, any GEP off of null results in a trap value if you try to load it.  Thus,
any load in the default address space that completes implies that the base value that it GEP'd from
was not null.

the operands. This allow allows the code to avoid doing a
recursive is-it-really-function-local check in some cases.

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.

For now it's still a command line option, but the interface to the generic

which does the same thing. This eliminates redundant code and
handles MDNodes better. MDNode linking still doesn't fully
work yet though.

 - 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.

MDNode cycles when none of the nodes in the cycle actually need to
be remapped. Also it uses the new temporary MDNode mechanism.
