- I believe more modern 'gas' supports a more enhanced set of arithmetic on
them, but for now the only thing we can do is emit them as data.

Add a InitSections method to the streamer interface.
...
The ELF implementation now creates text, data and bss to match the gnu as
behavior.
The text streamer still has the old MachO specific behavior since
the testsuite checks that it will error when a directive is given
before a setting the current section for example.
A nice benefit is that -n is not required anymore when producing
ELF files.

fix the asmparser so that the target is responsible for skipping to

the end of the line on a parser error, allowing skipping to happen
for syntactic errors but not for semantic errors. Before we would
miss emitting a diagnostic about the second line, because we skipped
it due to the semantic error on the first line:
foo %eax
bar %al

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.
