1c952b9cc9 Initial support for the cfi directives. This is just enough to get 
f:
        .cfi_startproc
        nop
        .cfi_endproc

assembled (on ELF).

5d4918dbd1 There are two reasons why we might want to use 
foo = a - b
.long foo
instead of just
.long a - b

First, on darwin9 64 bits the assembler produces the wrong result. Second,
if "a" is the end of the section all darwin assemblers (9, 10 and mc) will not
consider a - b to be a constant but will if the dummy foo is created.

Split how we handle these cases. The first one is something MC should take care
of. The second one has to be handled by the caller.

32a006e606 Try to resolve symbol differences early, and if successful create a plain 
data fragment. This reduces the time to assemble the test in 8711 from 60s to
54s.

af6b580875 Add .loc methods to the streamer. 
Next: Add support for the !HasDotLocAndDotFile case to the MCAsmStreamer
and then switch codegen to use it.

d80781b98b 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.
