comparison that would overflow.
 - The other under/overflow cases can't actually happen because the immediates
   which would trigger them are legal (so we don't enter this code), but
   adjusted the style to make it clear the transform is always valid.

Mark _alloca call as clobberring EFLAGS, otherwise some DCE might remove
other flags-clobberring stuff (e.g. cmp instructions) occuring after
_alloca call.

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.

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.
