94d026d157 Relax alignment fragments. 
With this we don't need the EffectiveSize field anymore. Without that field
LayoutFragment only updates offsets and we don't need to invalidate the
current fragment when it is relaxed (only the ones following it).

This is also a very small improvement in the accuracy of the layout info as
we now use the after relaxation size immediately.

f55f520a7a Patch by David Meyer to avoid a O(N^2) behaviour when relaxing fragments. 
Since we now don't update addresses so early, we might relax a bit more than
we need to. This is simillar to the issue in PR8467.

55cb19813e 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.

9215947c83 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.

50b6170457 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.

ae920bcc50 Add parsing for the Thumb t_addrmode_s4 addressing mode. This can almost
