Add support for parsing ARM arithmetic instructions that update or don't update
...
the condition codes. Where the ones that do have an 's' suffix and the ones
that don't don't have the suffix. The trick is if MatchInstructionImpl() fails
we try again after adding a CCOut operand with the correct value and removing
the 's' if present. Four simple test cases added for now, lots more to come.

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.

Next step: Only pad debug_line when the target is darwin. Add a FIXME to avoid
...
doing that if the target is darwin10 or newer.
This fixes
*) Direct object emission was producing objects without the workaround on
darwin9.
*) Assembly printing was producing objects with the workaround on linux.

fix PR8686, accepting a 'b' suffix at the end of all the setcc

instructions. I choose to handle this with an asmparser hack,
though it could be handled by changing all the instruction definitions
to allow be "setneb" instead of "setne". The asm parser hack is
better in this case, because we want the disassembler to produce
setne, not setneb.
